I made this game in pure js. It's a sokoban about a cat. There are 4 levels in the game. https://1akd1.itch.io/cat-adventure

Nice game without any errors. Simple, but enjoyable.

First time I tought some animations should be cool. But at second glance I realized that Sokoban style games not neccessarily need any anims.

I had to restart 3 times to complete all 4 levels ;)
