Hi SugarVoid, thank you very much for playing the game and taking the time to write a comment. I really appreciate that.
About the suggestions you proposed, I will try to tweak a bit the speed and experiment until I find a better balance between the "propulsion" and the fall speed, or alternatively I could add some items that can be collected and used, like for example a boost in speed or some kind of temporary invincibility or shield in case the speed is too high and obstacles become too difficult to avoid.
Regarding the floor, I could definitely remove it. I imagine you would like the game to end in case you go off screen? Meaning you crashed on the ground
