Hello game friend! I needed to try your game because my submission's title is only a one letter difference. You could say the difference between you and me is 'u' ;)
I liked your take on the theme, combining and splitting slimes. The art is very readable, and the square slimes are almost cute. I felt bad leaving some parts behind lol.
I think the controls could use a little tuning. I kept sliding off the edge because the movement was too slippery. Having checkpoints would also help the failures feel less frustrating. Flying off a ledge because momentum was maintained through a portal felt really bad.
Good job on this game! Well done in such a short time!
