Haha +1 for spawn camped in single player game. For a one person project, this was such a huge undertaking! Really impressive how much you got in, from animation, sounds, models, code! Congratulations! For constructive feedback, even after reading the instructions I was a little unclear of what I would be doing, so just jumped in, hoping to figure it out. Blue bar is oxygen, and when you run out, it starts degrading your health. I would have liked more feedback on what was happening there. My first time dying was because I ran out of health from suffocating (I think), but it was at the same time I engaged my first big robot and it touched me. I couldn't really tell what was affecting me, which was frustrating.
I love the idea of this game! I think I also would have liked to have been eased into it a bit more. Like a smaller level to learn what was happening, where I had to plant x amount of trees, and then the next level take over y amount of robots. That would have helped provide me a lot of guidance.
Great work though friend! Would love to see more of this!
