Really good looking game, really dig the art style. The setting is out of this world and it's really nice absurd humor. Even though the scenario is not something relatable, it doesn't take long to understand what you have to do.
The only thing I would suggest is to put a reference on the UI to know that LMB is used to aim when using mouse and keyboard. Bug wise, I would advise to include the arms and the gun in the collider so that we cannot shoot through wall by mistake.
For the sound design, the music is well chosen and SFX are well integrated.
Overall, it was a pretty enjoyable polished game !
P.S: if you can rate and comment my game too, it would be appreciated :)
