I really like the concept that Easy mode can prevent you from losing by also blocking you from winning. Like the other commenter said, it would be nice to have even some basic audio cues or keybinds for the mode switch, but the graphics are really nice. I liked that the easy mode elements fit the same aesthetic as the other sprites.
The physics were also grippy and momentum-based in a way that a lot of pixel platformers aren't, but which felt like they fit with the little rocky character. I was enjoying doing stretches of jumps with him, and could totally picture a really satisfying flow of consecutive jumps interleaved with mode switches.
Good work overall!
