I'm digging it so far!
I think I got stuck on level 3 for a bit. It would have been nice to have a slightly clearer tutorial about adjusting your jump height by bonking your head. It'd also be nice to have an indicator of what level I'm on. I think I was stuck on 3, but honestly I don't remember. Also, if I wanted to ask for help with my current level, I'd have to take a screenshot and share it.
Generally, the gameplay loop is fun! It's high-risk because you have to get the solution right from the start (very Celeste and Katana Zero-style), but restarting a level is easy once you realize you've messed up. The graphics are fun and cutesy, though I'd prefer Mr. Blobby (that's his name now, it's been decided) had a little more spring in his step. Jiggle when he lands, wiggle when he moves, and speeding up the walk cycle animation just slightly would go a long way.
The music is simple, but it fits the art style. It feels right. I've just had it going in the background for ~15 minutes and I think I could listen a bit longer. Not too much longer, but I could probably stand this music for ~20 minutes or so.
