This is an alright premise for a game but needs work. You need to fix the rounding issue for the points counter. Also what happens when you get bigger than the biggest cloud? After that there is literally no way to lose and the game goes on forever. You should implement some way to stop the game such as a timer or maybe a poison cloud that once you hit, you lose.
