Hello! Thanks a lot for your feedback!
I took me a big chunk of time to actually work with the graphics, because I manually recolored everything to fit the NES palette. (I will post on OGA the recolored assets along the ones I specifically created)
For the keyboard controls, I realize that they are weird for a lot of people because I use an azerty keyboard, which leads to confusing control schemes, as most people use qwerty ones. Maybe just translating the action keys to X, C and V may do the trick though.
PS: added controls notice in the description as you suggested, and I will rework them later
