The graphics are pretty nice but i have to say i don't really get the game. The atmosphere felt a bit... random ? I didn't get the music choices and while the characters were supposed to be astronauts (i guess ?), the environment had a medieval-fantasy feel. Also the discord log off and the homer "doh" weren't my cup of tea as they just added to the randomness of it all. (And the discord sound made me confused because i was actually on vocal with friends while testing the game)
It was a bit annoying to fall so much from the ground and i had some troubles with the controls. I think it would have been way easier to control them like you usually control a character, not like you control a tank. What i mean is that the W/S should let you go up and down and A/D makes you go left or right instead of rotating your character.
Overall i still think you did a good job but the game could be pushed in a better direction with a few tweaks !
