Once I got into the game it was an enjoyable experience with some detailed pixel art in a nice style. I also really liked how the lights were your health bar - it was a really nice twist to the mechanic. And, as I understand it, you made this game for two jams, so that is certainly impressive.
However, I feel there is a noticeable lack of conveyance for the player. For instance, I found it difficult to understand what exactly pressing the four buttons did at first. Even when I understood it, I found it a bit difficult to remember which button was which shape, and even when I got *that*, it was sometimes difficult to differentiate between the circle and the octagon.
