Really delightful game. You have such a good handle on your visual style - we actually remembered you from the Metroidvania jam that just ended! Loved the Ecaroh aesthetic then, and love it now.
After awhile, you start to feel pretty invulnerable in this game. Maybe a difficulty curve could be added, but regardless its fun to play nonstop. It would be nice to see the leaderboards working, but it's a small nitpick. This was really fun!
