Well, that was certainly interesting. The art is quite trippy (and fun!) and audio fits the overall atmosphere of the game. I'm not sure if there's only the one level, but I couldn't progress after clearing the first. It's an interesting mechanic that you only rewind what's within the circle, but there should be some kind of limit to how long you can rewind for balance purposes. Currently the enemies also don't deal any damage / I don't see my health anywhere.
Would be interesting to see what the finished game looks like! Good job so far!
