Hey, nice one! The Void Ball ability was a lot of fun to use, and chaining it with the dash to get tons of air was pretty cool. The artwork has a very hand-painted feel, I like it a lot!
Exploring was fun—there's a ton of thought put into the level design—and I feel like it just a little extra something could help incentivize it even more. Maybe some NPC's scattered around different places would spice things up?
Anyway, nice job!! Congrats on the submission :D
