Fun game! Controls were a little awkward, but nothing I couldn't get used to. Like another commenter said, there's really no platforming so hopping up steps should just be automatic. The graphics were nice. I especially liked how the big slimes turned into block shapes when you stacked them. Sticking the slimes together to make a big slime is a cool concept and clever interpretation of the theme.
Interesting concept and solid execution. Nice job!
