WHEN I PRESS SPACE, MY PAGE SCROLLS

Controls on this are brutal. And the dash is not killing the enemies in some cases.

The gravity/rise and fall is WAY too fast. The game suffers heavily because of this, not being able to properly hit enemies makes it much more difficult to pass through (not to mention how little the camera shows you). The game is basically silent except for jump/dash/kill sound effect (which all sound annoying). The fact you have autojump (which, thank god it doesn't dash unless you actually press the button a second time unlike some other games or this would be even lower on my list,) makes it very annoying to simultaneously want to have a trigger finger to dash but not want to hold it for too long (which you usually will assuming you don't hit an enemy and instantly die, more on that later...) and or you jump into something else flying above you. You also can't dash on the ground, making a lot of enemies walking along it a struggle to hit sometimes (again, assuming you don't get hit by something else above you). Death is constant, as all enemies kill you instantly and reset any sort of progress you made in the level at all (which means that you get to do the fun process of redoing everything you just did so you can die in the same spot again. Not a huge problem, but the controls definitely don't make it a fun mechanic).

This needs a whole lot of work before it gets better.
If you want an idea of a game with a fun dash mechanic, try the famous Overlord's Mansion

cool concept, although it needs better textures

no it isnt killing the enemies :(
