I don't like the core gameplay mechanic. I find it too forced, the "combined" moves syntax is hard to comprehend and it seems more of a chore than actual fun gameplay.
It's very strange. I plan 5 moves in advance and it does it like a turn-based game. It's interesting but would take some time for someone who is not use to it.
