Nice concept, I'd like to see more enemies and maps. I like that a controller is supported, though it seems like a keyboard/mouse is also needed to interact with the crystal and proceed to the next round(s).
Sure thing! Maybe if you just hit the crystal with the attack it has the same effect? I tried that and it didn't work so I just followed the keyboard prompt haha.
I really like the moodiness and vibe in your games, very dark and eerie.
