Hi,
First off I would like to say - Good Job. This is an amazing game for only being developed for 2 days. I rally liked the sound track it was relaxing and kind of misterious making the atmosphere better. The underwater part was amazing and beautiful to look at.
The only things I can say I had problems with are the paralax effect on the background - it made my head dizzy but I guess you like it and the fish. I died approximately 20 times before completing the game ( I guess it was a skill issue xD).
The game is amazing. If you can do this much in 2 days I can't imagine giving you 7.
