Things I liked, You had a great artstyle and I really enjoyed swimming around and trying to get past the clownfish lol. Your idea for rewind as in playing in reverse is cool and I would love to see some extra things done with it.
Things I didn't like, I feel you could have benefited both from a menu as well as instructions. I didn't really know what the buttons were and I had to figure out how to shoot. In addition it felt way too easy to get hit and die, the one bubble for initial health was useful but I feel only served as an extra hitpoint and nothing else besides that. If it was something that came back after awhile I feel it would help out immensely.
Overall though, its a pretty fun game and you should be proud of how much you got done in week. Good luck with any future games!
