Thanks for your response! I agree that some bugs were left unsolved. I tried weighting the spawning system for the obstacles a bit so they would appear more regularly on the bottom, but I completely get what you're saying and I probably could've done with weighting it a little heavier on the bottom. I also struggled to come up with a solution for the diamond, so if you've got any ideas for that, that would be much appreciated :-) Thanks!
Cool! I think that could fix part of the problem, I know sometimes the stars end up inside the obstacles because they are a bit faster than the obstacles, but it could be that your idea fixes it enough so it happens so rarely it doesn't matter. I'll have to implement it into the game and see how it goes. Thank you!
