It's an okay game with some issues.
First of all your UI tweens/animations don't scale well so I was not able to play on fullscreen (1440p). was able to play in browser without going fullscreen.
The game has a lot of dialogue. I think too much. Took me quite some time before I could play the game thanks to the dialogue, and my gameplay was often interrupted with dialogue. Wasn't able to get to play the game enough to understand what's going on during the first playthrough. Always getting interrupted by dialogue or level ups.
The game also doesn't have challenge. The oxygen thingy I forgot because I didn't have to think about it, all cats dying to one explosion also made it quite easy.
But good job on finishing it!
