Hello! A great entry. I liked the music (although the loop could have been longer or have a better transition). Controls were a little bit weird? Why not have WASD as controls, and space as shooting key? But that's a matter of taste I guess.
Theme was definitely met, however, I am not a real fan of the game mechanics to be honest. Firstly, the range of the attack is way too short. I died very often trying to kill enemies. Secondly, why even bother killing enemies? It just consumes energy and you do not really get any real benefit from it.
What I really liked though was the structured and solid tutorial, and the platforming itself was also fun! Maybe make enemies drop energy (or make killing enemies necessary), make the range of the attack longer, add better use for the jetpack, and then you could get a solid platformer!
