Your game design was awesome. Every new type of wall was quite well explained through its mechanics. Even though you overslept, it was a fun game overall. Heck, you even made a transition between levels. I wonder how it would've looked like with more development. I honestly would love to see this game developed further, since your ideas seemed to be really creative.

Although it pains me to see this, I don't think you adhere quite fully to the theme of the jam. Sure, the game's name was "only one shot", and yet you are able to use the blue thing -i.e. another bullet- in multiple levels. Rebranding it as "it gives you back your bullet"  didn't do it for me. If you are gonna keep polishing the game, i humbly suggest that the blue thing is replaced by a magnet, and that the used bullet return to you by using the former. That way it makes sense at a more intuitive level.

Overall, a really fun game. And isn't that the goal of videogames? Great job TatoPotato.
