Nice game! Liked the sprite for the main character and all of the sprites animations! VFX and PostFX after the twist also adds to the overall experience!
I found player movement to be a little bit rough, especially the gravity modifier after the jump and inertia. It creates some cool power fantasy if you time your jumps and slides correctly, but once you hit the wall — the whole speed is dying and recovery doesn't feel great.
The idea for the game is really cool! I wasn't that great in my first attempt and I could meet the requirements for the end pretty easily, but it feels like the game could benefit from more mechanics, levels and even characters. Good job!
