That's one of the best entries I've rated so far.
Gameplay is really fun, patterns are getting really interesting above 5000, and it perfectly fits the theme.
Art is really good, almost everything have animations. The in-game tutorial was a good idea. Music was nice too.
I think at a point, the patterns change too often (like every 2 seconds) and that become too hard. It would be probably more satisfying if the pattern change frequency had a limit, and after some time, only the frequency of lightnings was increasing.
This being said, the game is amazing !
