Really good game. You must track the battlefield and your next attack at the same time to position yourself to the best place to attack and I really liked that. Also the randomness in attack order and rooms adds game nice dynamic so it doesn't feel boring to play again.
The difficulty was also really good for me, but once I died by going to the black rectangle, I guess that was some hole in the ground, but maybe with some slight indication of it it would be more obvious that I can't go there.
But overall good game, that feels nice to play.
