Well, I'm currently using a closed-source paid sprite tool for unity3d, can I use that or should I better find a free/open-source solution or make my own? If i should make it myself, can I make it before the comp? No game logic or anything, no assets, just a tool for handling sprites and animations.
Also, the question about song covering is interesting too. Can I use myself-produced cover(will be made in those 48 hours, ofc)?
