Played your game. I assume this will be updated in the future? If you ever upload an updated version I would love to play it!
Pros
Good use of entities
Simple story easy to follow story
Character creator enemies look great/good use of character creator
Cons
Some entity placement looks too uniform/need to be spread out and randomised more
Map design is a little confusing, resorted to climbing to get to places
Maybe include a radar with objective markers
Lacks any sound or music other than the player and weapon sounds
Enemies were too overpowered/use of sniper rifle helped, but could find little ammo (add more sniper ammo)
Add more variety of weapons (1 or 2 more would be sufficient)
For some reason the game would not finish once I reached the ship
I also noticed a few entity/texture clipping were objects were not placed together correctly
If you ever update this with my suggestions I would love to play it (maybe add more levels too)!
