A fun little game that has you run around and collect raindrops.
It's certainly something I haven't seen before, something new and refreshing. It's basic, but it's something to pass the time.
I think the best thing you could do is one of two things. A. Make a scoreboard so other people can compete and try to get the top score (That's how most arcade games do it, right?)
Or, you can go with option B: Make it a larger game. Make some levels, add a limit (You need at least __ raindrops to pass this level) and make it more of an arcade game with harder and harder levels as you go along. This is a good start and it gave me a little smile, though.
