The game is very fun and interesting. A couple of tings to improve would be the controls and level 4. For the controls Isuggest putting the jump button on the W / Up Arrow Key because since you have to use the mouse for this game and move with either the arrow keys or WASD at the same time, adding a 3rd key on a completely different spot feels very clumsy, it feels like I should have 3 hands. And for level 4 just dont make the rising platform kill the slime if it touches the ceiling because I already figured out the puzzle and having to repeat the steps every time only because I was a bit too slow was very frustrating. Despite this it is still a very enjoyable game.
