Bold of you to make a 3D game in a short time. This game remembers me the first PC games I played. Nice job. I couldn’t finish because everything is too far and everytime my power/oxygen ran out and I had to start over.
Thanks for giving it a try! Were you able to get any upgrades? I didn't have time for any tutorialization, so I was just hoping people would notice the text in the green area for the upgrade shop.
