A metroidvania where you have to collect three keys (adventure).
The platform controls in this are really good, the wall jump especially feels great to use.
The air boost is a REALLY good mechanic, it's so much fun to go insanely fast with it. Though, it is a little off how there's no visual feedback for it. That's perfectly fine, but something like a sprite or a burst of particles would make it feel much more satisfying.
Speaking of visuals, I like the little character you play as. I also find it a little funny how the helper that follows you around is just a big yellow circle.
