Until Zero
A quiet 5-minute puzzle about turning off the lights. Click a power cell to take one charge; at zero it blows and drains its neighbours — chains cascade with falling tones. The reactor core must be the LAST light to die. Nine decks, each one shutting down a real system: lighting, gravity, life support… and, eventually, the interface itself.
Mouse — click a lit cell
R — restart deck
Esc — settings
(One deck has no restart. You'll know which.)

so good, soc razy to make this in one day, congrats!!
Super cool Game especially for an Early submission, lots of fun and cool idea
thank you !
Really nice game, even more for an early submission.
Thank You!
Pretty good for an early submission
Thank you
Wow, pretty cool, very fast submission. I didn't read the instructions, but I managed to win by clicking the biggest number near the top most of the time. I had to restart a few times on the red level but got it the third time around. Pretty cool concept just needs a better tutorial so I don't feel like I'm cheesing it, haha
The visuals were very nice as well, felt professional
Thank you! I’m working on improving the level design. Since I have experience with tower defense games, I’ve developed algorithms to automate the level design process. I’m aiming to improve the visual quality a bit more with Love2D. I also feel like I want the game to have a bit more of that “game-like” feel. Plus, I’m thinking of making the puzzles more challenging. But I’d like to emphasize the “countdown” aspect a bit more.
Yeah, I totally get that. The trickle-down effect feels like the closest thing to a countdown; maybe a more dramatic animation as each light disappears would make it more obvious that it is counting down. Or a level with a light that increments down by itself until reaching zero.
Cool puzzle!
Thx broo! Play later too :)
