Decent game; I like the art style, the blocky, monochrome aesthetic is really nice.
The difficulty ramp needs to be revamped though, making it a bit easier in the beginning.
You should also consider making the hitboxes for the hazards smaller; at the moment, the collision feels a bit unfair, as you're able to die without the player sprite even overlapping the graphics of a given hazard.
I love how speeding up the game increases your momentum, allowing you to traverse larger gaps; it's quite creative, and leads to a lot of interesting level design opportunities.
Yes, the difficulty need to be changed, 100% agree on that.
The hit box is slightly bigger than the sprite art (due to the empty space on the sprite), I will have to go back and make a custom smaller hitbox for the hazard. I am also thinking of changing the hitbox of the player to be slightly smaller so that the game is more forgiving.
Thank you for the feedback!
