In the blue rocket game: if you die a couple of times the game gets SUPER laggy and unbeatable, but if you leave the screen and return to it it becames normal again (which means redoing the whole thing again if you had trouble in the last wave... looking at you 4-3 !!)
Other than that the whole concept was very interesting and I wonder what you'll do with this in your following works.
I loved the art of the overworld, but the music was just ok (the soul of 8-bit music is in catchy melodies that don't repeat that often to the point of annoyance. None of the songs were annoying, but neither lifted the gameplay experience as they could - or as I think a song could... why am I still rambling about music?)
