The concept of changing the resolution is really clever! And the art looks good and makes it easy to differentiate resolutions.
I do like how this concept interacts with the gameplay, but I think it could be improved. Right now it’s not really intuitive what obstacles can be ignored. You kinda have to remember it, and the fuck that there are different objects in the same group doesn’t help. Some sort of color-coding would probably help.
It would also be a good idea to give the player some amount of leeway but adding HP, so that you don’t die in one hit and have time to learn the resolution -> obstacle interactions.
Overall great job!
