The art style of the game is really nice and the sound is great i really enjoyed it!
A few problems i did run into, sometimes i would just get stuck moving for no reason possibly an issue with the collision of the level. I also found it at times quite hard to jump the slimes especially if they are moving away from you, if landing on top of the slime you also lose multiple health rather than losing 1 heart and being pushed away from the enemy.
I did at one point fall down a hole and there didn't seem to be a way to teleport back to the start so i was just stuck running around underneath the level.
Overall a great looking game with some cool features!
