That tremendous amount of work and effort has been put into creating this game is obvious - great job. It is not easy to create something like this in Alice, and your use of sprites is very innovative (at least for me :]). The graphics are well-made too, and the fact that you used programs other than Alice is a good example of how Alice is not only limited to its own gallery
.
I would have to agree with Ch0pstickS though, as Davario does seem to move across very slowly, and gravity is very light. Maybe it is just my computer, but I couldn't get past the first level, due to those annoying turtles :S.
Nonetheless, I applaud your team!
