Really interesting idea. The game needs a bit more polish though. For example, I coudn't see sometimes where I am jumping because the camera was too high up and the shooting mechanic wasn't explored properly.
I had sort of toiled with this issue myself about the jumping but opted for the game to look like this purposefully to feel more like a retro game, the reasoning is similar with the shooting mechanic, I could have done but didn't want to lose the GB soul since this was the whole point of the Jam :)
