ROTA - A Minimalist Puzzle Game - free for iphone, ipad

Erich Kohlweg's game ROTA reminds me a little of the World's Hardest Game, which I reviewed about 6 years ago.

The object is to shoot the red dots from the spinning black asterisks.   Naturally, there are obstacles, reflectors, wormholes etc. There are 50 levels and I did them all fairly quickly.
