The game is definitely a cool take on the theme, but it is difficult to control at times. When using the arrow keys to shift abilities and using A/D to move, it felt hard to coordinate my hands for seemingly simple jumps. Maybe if W/S were used to switch abilities as well, then it could be easier to use? Hard to say.
But still, the concept of the game could be the basis for some tricky puzzles. Would like to see that!
