A surprisingly fleshed out game for a student project! A good variety of levels, enemies, obstacles and music really makes this feel like a full package. The timed aspect gives the game some replayability, and the story ties it all together nicely.
The only criticism I have is that I think some of the levels could have been a bit longer. In particular, the last level seemed a little too easy to clear in the time limit despite how dire the cutscene before it made things sound.
