Loving the art style of this game, it's giving me Adventure Time vibes that I dig.

The colours are bright and every single sprite has a lot of character about it. The animations are also on point so well done there.

The variety of enemies, their sprites, animations and attacks are all pretty awesome considering the one week time frame and the backgrounds that often vary just make the game come alive. 

The music and sound effects are good. Not much else to say there though. 

The overall gameplay is great and satisfying, not too hard, not too easy and it flowed really well for me. However, I barely used the slow time ability and didn't quite know what the attack/rage like ability was really doing. I think this might be down to button placement though and my feeble fingers not being able to press Q or E while moving!

They were neat abilities, but I didn't really need to use them. The dash was a lifesaver though.

The boss battle at the end had some cool mechanics, although I did kind of cheese the boss by taking the damage and just swinging till kingdom come.

Finally, the story has some cool ideas to it but I kept finding myself expecting to find and save another slime who'd join me or something but instead it seemed they were all saved at the end? Perhaps this was the initial plan as the theme only really fits when you consider the story. 

Still, the game is super impressive with it's art, animation and variety of enemies and mechanics, so good job.
