Unclear instructions, but good minigame/teaser
It was very unclear at first that I had to input the four-beat command, then WAIT four beats, then input the command again. I was trying to keep the beat, and was keeping the beat pretty well, so I didn't understand why nothing seemed to register. The character's commands each lasted less than a second because I was failing so badly.
However, once that was figured out, the game itself was quite enjoyable. Made me consider getting the full game.
