Very unconventional gameplay (stars being projectiles, hp, and jumping assists - I love it, it's weird in the best way), pretty to look at and very professional feeling physics. A lot of platformers aren't satisfying, but the precision in this one feels fair, and the tutorial stage helps a lot.
Snail-chan is adorable, everything about this game feels like a vintage SNES or possibly Sega Saturn title in the best way.
