Seems a lot of fun so far!
I think I got about half way, but I've gotta run for now.
Just wanted to give some first impressions:
Love the choice of art assets - the tiles and backgrounds work well with the music, and give the level a playful feeling.
A lot of the enemies you chose are fun and interesting as well - I don't usually see the ball-throwing enemy used often.
One problem I did run into was a vertical section that has a wall of yoku blocks at the top.
The timing was funky for me, and I couldn't figure a good way to get past it the first time.
I ended up dying at some point, and the next time it worked out so I could jump through.
I might be able to use the saw to climb up and wait out the blocks' timer, but I've never actually tried to scale yoku blocks before, so I'll have to try that next time.
I intend to come back to this one to finish the level and leave more feedback, but that's what I've got for now.
If you don't hear back from me by tomorrow afternoon, shoot me a private message as a reminder.
