Oh heck, sorry for not answering to this after such a long time. We pretty much abandoned the game after the jam. It was supposed to let you combine stuff and let you keep them after rewinding time and so you would have been able to create more and more stuff but we didn't manage to do what we had in mind and had a lot modifications at the end to try and make it more fun, but we weren't happy with the game.
Graphics were actually made by the other buddy who worked on this as well ^^, but the audio was royalty free audio from the internet.
