I think the time machine concept could be a good one for the jam, but I'm not sure how time travel works in this game. I might have missed it. The LMB attack was pretty clear, but I could not quite get the hang of the RMB, probably my fault, but I didn't really get what it did (maybe it's the time travel piece I missed?) The spinning clock in the corner looked cool. The low-poly game objects in a higher-poly environment felt a little disconnected; maybe choose one style or the other, but not both. (I have the same issue in my game, a detailed bg image with my waaaay less detailed art on top, just doesn't work as well). Good job getting your game done for the jam, especially in 3D.
