Thanks for the ideas. I can't really add them to this project, just because I've started working on a new game. Only Up was sort of just a test project so I could get familiar with using a new engine. I also sort of focused on the game running smoothly on any computer, getting a smooth frame rate on a Chromebook was kind of the ideal benchmark in terms of computer power. That's why the theme is low-poly and not realistic. On that same note though, in my next game I will be sure to add a better sky, at least with a sun, and something that will fit with the style of the rest of my assets. I do agree that a different movement system would be great for originality. I will definitely add one to my next game (a FPS) if I can think of something that's not crazy overused but can just add to my current one. I will also work on adding some kind of plot/puzzle to it as well, I'm not sure how well that fits into casual multiplayer, but I'm ready to try.
