Art and music are great, TBH kinda reminds me of my own submission lol. The intro was pretty awesome. The limitation use and concept are great too! The game feels responsive and intuitive, especially with the sound effects (tho some more VFX is always appreciated). The movement makes the game kinda difficult, especially with the inconsistent jumps and wayy too fast movement, that paired up with level design being a bit unforgiving for starters kinda makes the game fall apart, as BiPi said. I feel like if the game was made easier and polished a bit, it could really shine! Great work!
