A good game, but I haven't like these things (only my opinions of course):

the player fall is too slow

the player speed is the same of the aliens, if you have an alien too close you can't manage the situation

one time during playing I wasn't able to run and use jetpack both in the same moment. I wasn't able to reproduce the condition again, maybe a bug somewhere?

Could you upload your game as html in the itch page, to avoid to download in the pc your game? I'm a bit lazy but I think that I'm not the only one around :)
