Your control scheme (especially on Keyboard) is horrible, sorry. I'd really prefer it to move the camera with mouse movement, instead of Q, E Up and Down, but I guess its designed for controller, as you said. If you're on Keyboard, just bind jumping to space, you already got camera snap to F (which isn't really needed anyway) no need to have it on space aswell.
There not being any Air controland railings or other small plattforms makes it very difficult to move into direction to jump properly, instead of just straight up. keeping some momentum forward even when running into a wall before jumping could help with that.
I also could walk through the white Spikes in the beginning, not just land on them. Is that intended or a bug?
Game has heavy Framestuttering during level loads it seems.
Gave up on the Open sky level, I'm really not into those hardcore Jumping/frustrating platforming Games.
The hoverpads(?) and jump refuels where nice tho, obviously could do with some more fitting models instead of white cylinders and green Spheres, but I liked the mechanic. Also cute Robot, but I wished it'd have some more fluid animations, bending forward while moving and hovering or something, even if it may not make much Sense for a Robot.
Still, nice little Prototype, If you fix the clunky movement and camera (again, might not be so bad on Controller) I could see this being Fun. Maybe.
