Thank you! I am actually planning on adjusting the difficulty modes a bit so they are overall easier to get through. I think I know what part you’re talking about in the upside down level, and I will definitely fix that too, along with the part with the spikes. I am planning on adding an arrow indicator above the heads of the enemies when they are able to be damaged, at least for the first few times, that should make it more clear. I’ll also fix the fullscreen issue. Your feedback was very helpful, thank you so much!
