The game's premise is unique and has potential. It reminds me slightly of Dust Force in that it is rare for janitorial services to be turned into the setting for a game.
I liked the CRT-like and chromatic aberration post-processing effect you used.
The music also had some good energy to it.
The splash screen art of the astronaut is also quite well drawn/painted.
However, it'd be good to have keyboard controls too and not just mouse controls.
Also, when I tried the game, your procedural generation system made the second level impossible to get through as far as I could tell. The terrain seemed impassible.
The game feels incomplete and I'm guessing that it indeed is and that you may have moved on to other things by now. I just felt like giving you some feedback anyway though, to be supportive of fellow creative people.
Good effort and best of luck!
