I wish there was more to this simply than just 'see how long you can last.' It might be interesting to have different levels, maybe the obstacles speed up in some or maybe introduce new obstacles, like maybe some move side to side as well as coming down. I also found the red ball rolling away from me at times when I didn't even touch it, resulting in it hitting the wall and me losing the level. I'm not sure if this was intentional or not, but it was quite frustrating. Maybe if there were the levels introduced that could be an interesting thing to add in later levels as an intentional design. But I think overall this was a very good attempt and I still had fun. :) Good job!
