I agree with what others have said about the umbrella tilting being a little bit annoying. Maybe it would be easier to see and correct if the umbrella tilting was constrained to one dimension (as in it only tilts from left/right).
I kind of enjoyed waiting under bus shelters, even if it diminishes the difficulty, it really captures the experience/frustration of momentarily seeking shelter from the rain. Ultimately I enjoyed this more as a caught in the rain simulator than as a skill game.
Good work, really well put together!
