The crystal felt out-of-place art wise. it didn't feel like it matched the environment. The control is taken away from the player too drastically, for a jam it's works, not sure if this could work out post jam. The art in general felt imbalanced but good attempt! And in game tutorials are critical, specially for a game like yours, I feel reading tutorials elsewhere kills the game instantly for me, and when it's not in-game them well that's a big red flag for me! All the best!
