Thank you so so much for taking the time to play the game and give us this amazing feedback! As I've mentioned to others, we're working on a polished version to release after the voting ends based on stuff we didn't have time to implement and feedback, so it really means a lot! The whole issue with movement speed and the void hitboxes will most definitely be adressed, as well as a tutorial so newcomers can get a better grasp of the mechanics at play!
Thank you so much for checking out our game!
