Really nice game, good work.
The dissolving platform is a nice idea for the game. The background and lighting were very good, too.
The platformer could be improved, though; it feels a bit boring after a while.
The enemy hitbox sometimes feels a bit janky. I kill the enemy, but it also kills me when I hit them on the edge. It could be nice if you made some checkpoints throughout the map.
Also, the spinning cat, haha
