I'm definitely not disappointed by the game, but I was a bit surprised that there wasn't any stages of Perk size between those that you'd get by merging 100% slimes of that Perk. I was expecting there to be, like, a size between 4 and 8, or something. I definitely get why not, since that would be a lot more art variations to do.
All in all, neat little game! Experimenting with the slimes was fun, and it's nice to see an expansion game that incorporates lips. I'll definitely be keeping an eye out for the sequel.
