Very cool concept, it took me abit to understand how the jetpack works, and it always makes me flinch when i’m kind of have to fall into the void to advance, but once you get the hang of it, it’s quite cool.
That beeing said it’s way to hard for me, i’m not a platform nerd, so this was definetly over the top. I quite after about 200 deaths (in level 4 i think).
I think some things are nedlessly hard, like the level before, with the free flying blades and fuel tanks, which was very interesting, but the goal still had spikes around, which is quite mean i think :P.
In a platformer like this i would also like to have additional control options. I prefer using the arrow keys and jump/boost on spacebar, which would make it a bit more comfortable to play. You could just add double bindings here, since you don’t need the other keys anyways.
