This game really uses the only one and makes a fun puzzle games.

Pros:

+ Cute, Fun art style

+ Simple Controls

+ Good adherence to the theme

Cons:

- Audio for gunshot was too loud

- Game loops endlessly, with nothing to signify when you beat the game, other than seeing the first level again.

- No UI to show if you have a shot or not (Spent 30 seconds trying to figure out why I couldn't shoot before realizing i had no ammo)

Overall you did a great job, and my cons are mainly just me trying to give feedback on how to improve the game further.

Please check out the game my team and I made:

Thanks and great job!

Super concept, I loved piling up bodies to make my way through the level!

It follows the theme of the Game Jam but the mechanics of reusing dead bodies seems to me to go beyond the concept of "one life", because in practice you have so many. You don't have debuf if you die apart from start again, and in some cases it is also mandatory to die, which makes it impossible to finish the game with just one life. The "one bullet" instead is better, and the fact of creating a zombie every time you are killed by one of them prevents you from killing all the enemies simply by shooting and then committing suicide, because you do nothing but cancel what you just did.

The graphics are very beautiful, the controls respond well to the inputs and the sound design is excellent.

Anyway congratulations, 48h are few and this game is very well done.
