I don't know if being able to crouch jump in midair after a glide is intended but it had me confused for a while at the 2nd jump. Also seems pretty useless since it completely kills all your momentum. The part with the jump refuels is really hard with 0 air control. I beat it anyways beacuse I am a god gamer. Nice helicopter. Looking forward to catching those pesky rogue scientists.
ps: I glitched through the elevator floor after the part with 3 orange platforms over the green stuff. It never came back
pps: I'm all for "figure it out" but I think you need some explanation for the control, I just figured out you can move forward when you "snap" to the ground
ppps: Some indication that the spikes are about to go up would be nice. At the moment you have no idea when to jump to avoid dying.
