I really like the idea of switching between modes, not only to change the map but to also change abilities. The timing is tricky but very fulfilling when done right. I think the hardest part was switching modes quickly while still trying to use directional controls. This is where a controller would really shine, it would free up some of my fingers to let me get the timing down correctly.
The character controls well and feels similar to Celeste. The levels are hard, but show off what is possible with the concept. Overall, good game.
