A extremely unique take on the genre, a very nice attempt at really standing out from the crowd. I think that there is a relatively unexplored niche with this sort of play, outside of games like Fez etc.
I won't critique your game as I normally have with the others, as the version I've seen isn't complete according to the comment from the Developer. But what I will stress is the importance of Source Control, using your case as an example. I've told others that for short term games, cloud backups are entirely viable since they will not be expansive and sizable projects. However, not having anything is a tremendously risky move. Everyone in the team needs to have various versions, and the whole team should take responsibility not just one person.
It is a shame that the work was lost, because this is a really interesting take on the genre. Hold on to this idea, cause there is something publishable here. If you want a more game design-y discussion of your game, come find me before or after the lecture on Monday.
