I like the way all the powerups felt. using the groundpound as a method to reach greater heights was a genius idea! when I used the ground pound near the start though, the game crashed, but I think I got most of the powerups before then. If there is a boss or something else that I'm missing after obtaining the ground pound powerup, please tell me and I'll return to finish the game. Great 3D Metroidvania! Its uncommon for a jam game to have full sound and have this much polish put into it.
