Nice visuals, music and sound effects.

The main way of dealing damage is aligned with the jam theme.

Some suggestions for improvement:

- Add a previous stage in the game, with an enemy that requires less lives to kill, to teach how it works. It got boring trying to kill the boss multiple times with different number of sacrifices each time until I figured I had to go all out.

- The 'sacrificing' part got really repetitive. The only fun part was the 'activation' run. Find a way to make the whole game fun. Maybe add an option to retry from "last life" or "from the beginning".

- Consider changing the quit and reset button bindings. I managed to reset by mistake all my progress when I was in the final run trying to press E to activate the cat balls. The same happened with X as I was trying to run away from the boss in yet another final run and my finger slipped down from S to X and the game was closed. VERY FRUSTRATING.

Well made Game!  I liked the Models! Well done!

Nice and simple. Got top-tier visuals and the sound is nicely selected! The puzzle took just the right amount of time to figure out, but I just wish it expanded on the idea further.

Simple, beautiful, great music, just awesome!
