I loooove the art style here. I decided to play this one because of the images of it I saw when i was scrolling over the game on the submissions page.
As for the gameplay, I do think the movement is too slippery. Slippery isn't always necessarily bad, you can use it as a mechanic to make a game harder, but its important to find the sweet spot of how slippery you can make it to still have it be fun and still feel like the player has decent control.
Good submission! I was able to get a score of 48
