This was awesome! The AI was honestly pretty damn good at what it does. The gameplay mechanics are very nice, though the Ability seems to charge up too slowly for using it to be viable? I loved playing as Nitori and building icewalls everywhere I go, though cat-and-mouse with two Cirnos was also pretty funny.
Also, attempting to create a ice-prison for yourself (highly possible for Nitori) makes the game lag massively. I guess it's an AI pathfinding issue?
Overall good work on the game!!!
