This art style works really well for a platformer. Gives me Celeste vibes, in a good way. The level design worked well too, and I think you have a fun concept layered in with all of this, but it needs a bit more of a warning when the controls are about to switch. Like a timer or a visual que. I think the controls currently switch every so often, and my strategy was to just wait until the controls reverted back to normal to continue haha. Maybe that's an intended strategy? I made it pretty far but then I think I jumped out of the level?
All-in-all, nice work!
