I like the idea of your luck literally running out. that's the first time I've seen that in this jam. very playable game. would have been cool if the umbrella let you float for a certain amount of time before it goes inside out (perhaps relative to the luck meter)
my biggest gripe was the timing of the pre-lightning. I didnt feel like I had quite enough time to react to it, so I basically got hit by every strike.
overall: great work!
