I've been waiting to try this one ever since I saw a gif you posted on the jam server. Love the vibe right from the main menu and when I opened the Controls menu, I don't think I've ever seen quintuple jump before so I was eager to try it out.
Quintuple jump + air rolling didn't disappoint, and the rising sfx for each jump input is a pleasant touch. Made me think of a combo system where that increases based on trying to stay in the air while retrieving the projectile for as long as possible.
Edit - just saw your creator page - is this like a series you've been working on or one big project released in batches?
