Last Fuse
I made a tower defense, but plot twist—you’re defending a nuclear bomb. It powers your defenses, but the more you use it, the closer you get to meltdown. What could go wrong?
The game tempts you with risk-reward mechanics like Overdrive, which boosts energy but rapidly increases heat. Push too hard? Kaboom.
The bomb is your greatest asset and your greatest threat.
Your crazy engineers constantly throw problems at you.
Every decision shapes your survival. Will you take the risk for extra materials, faster turrets, more workers—but at the cost of rising heat, or play it safe? Choose wisely!
Submitted for Brackeys Game Jam 2025.1, theme "Nothing can go wrong". Check out my design process here!
If the game runs slow, go to Settings > Disable Global Illumination, Water Reflections and Shadows.
I worked really hard on this game and am considering to work on it after the jam if there is interest. It may have only been a week, but I have so many ideas for it - Maybe the bomb is alive and has personality, bomb types, bomb upgrade paths, perks, permanent tech tree, different map layouts, turret abilities (frost, fire), maybe even weather. Okay Imma stop before my brain explodes.

Many many many bugs but a fun enough game, shame to see some content will be pay walled but overlooking that for a moment-
Planes don't check if the right tiles are valid to let you build (can make one of the endings harder) and battery capacity goes up more than it says it will when you upgrade. Also if you die to heat in endless mode, you're almost softlocked just claiming launched bomb goods?
Oh and would be good to change the cancel key to something other than escape.. the same button to unfullscreen the game
Looking at the roadmap (and can definitely feel the Frostpunk influence, don't stray too close, keep it distinct) not a fan of the perk idea with fragments, the current system (Rogue legacy-esque) is definitely better
In general, good luck and may development go well
Heya thanks for trying the game!
Can I ask what bugs you faced, other than the plane and battery bug? Thanks for reporting those, I have just put out a new version (v0.14) that fixes both! If you die in endless mode the game should end and force you to restart a new save - if that didn't happen then it's a bug.
Will think about the ESC key - I would have put it on Q but that's for toggling the bomb. The game is designed as a downloadable game in mind so the shortcut keys are built for those platforms.
Understood on the frostpunk comment - I'm more inspired by TDs than Frostpunk actually, so I am not too worried about it!
What do you not like about the perk fragments? The game is still evolving and still in the idea experimentation stage, so I am open to feedback and how to make it better!
No way I could remember all the bugs throughout all the time of playing but one other at least was that the fire tornado didn't seem to work as intended, could build everywhere there initially, destroyed it, then deconstructed turrets to build other things, and all the inner squares where the tornado was (that I could build in before) were no longer accessible at all (and also the now despawned tornado prevented being able to click on the centremost square to deconstruct)
Esc key could pretty easily be bound to accept a secondary input from like.. h, couldn't it? Or even backtick key to the left of 1
This is all old memory now but the fragments feel too gambly, too non-concrete, I can't quite remember how I would have worded it but I suppose that how hard it is to earn would be far less clear (possibly hidden chance rather than just a concrete amount of things) and also that you can't at any point focus your progression or choose where to go about it
Ah the fire tornado was a preview of islands - I'll temporarily remove it and add them as part of the island update. Thanks for sharing about this. Aside from that I believe I've fixed all other bugs in v0.14.1, which I just put out.
As for moving ESC to backtick / H (Used for help currently), I think putting it at any other key isn't the most intuitive - I suppose an extra tutorial could be added to teach web players that specifically, though it would make it inconsistent between the downloadable builds and web build. I might deprecate the web build as the game is now on Steam.
As for the perks, I'll probably have to actually implement it so that everyone can try it out and get a feel, as I think just explaining the full system here will require its own post, but understood on all your points!
good work!
thanks~
One of my favorite games i tried so far in this Jam! I really like the concept and adding those special events with the people adds that extra spice of randomness and temptation to it haha!
One Critic tho at the start of the game where it explains all the UI AT ONCE it just feels a little clustered and overwhelming, but thats just me. Besides that i really enjoyed it, keep up the work o7
Hey there, I fully accept the critique! I will work on improving the tutorial post-jam - I am open to ideas of course, but for now my concept is to get rid of the middle 5 screenshots and do it step by step - e.g. I'll circle the bomb and say "Protect it from enemies" -> "Press 'Q' to generate energy, but it also heats the bomb" -> "Steel is your primary resource" step by step than all at once. :)
Also YES the events! That was so much fun to code and write the dialogue for! I felt like this evil mastermind doing my best to make it as tempting as possible for people to pick the "Nothing can go wrong" option HAHA.
Honestly, one of the most fun games I've played in a while, I haven't sat down for 1-2h to actually play in years. Massive Kudos to you, the best jam game I've ever played. As another person suggested, you should, imo add camera rotation, maybe mess around with the map to be able to have space on the other side too.
Heyy, thanks and good suggestion! I will add camera rotation after the jam period ends, and possibly it will work well if the game gets bigger maps (?). That way, you can even build behind!
Also, I'd recommend you mess around with the font, seems a bit low quality in a way, did you use TMP?
Hey there, yes I used TMP, what did you observe? If I can understand what the issue is I can try to look into it!
Bro you make the most unique game, please bring this nuts game to steam to:) i have havendock, waiting for stormbridge and now this! You are a madgenius with this ideas !
Haha wow! thanks for such kind words and for the support! I truly appreciate it, there is still a lot of ideas I want to do with Last Fuse after developing it for the past 7 days. I will also consider the possibility of a Steam release, so stay tuned!
really impressive! loved it! kind of felt like a very rapid version of frostpunk with a cartoony vibe :)
honestly i can't think of much to suggest, other than a way to rotate the camera (i don't think there was one, if there is i didn't notice it).
great job, i'll be sure to rate it when the ratings start
Thanks! And yaassss hello there fellow frostpunk player!
You can hold right mouse to rotate, though I restricted camera rotation to just up/down since WASD moves the camera left/right to see the sides. Would you prefer being able to rotate to see the sides as well?
And thanks for the kind words, will be rating yours too!
Yeah I think the up down only rotation feels weird, especially with the frostpunk vibes, you want to be able to rotate around the bomb as it gets built
Got it, I didn't want to increase complexity for the player initially as not everyone may come from the strategy genre and locking the view point prevents accidentally navigating to an awkward view point where they cannot see the enemies or bomb (a player I saw went to zoom in all the way and didn't know how to zoom out, then got lost when the offscreen enemies killed them).
Nonetheless, let me experiment with that!
