Very interesting take on Tetris, I suck at this even more than I do in normal Tetris, so I didn't get to any really wonky parts. What I can say is that the blinking with the appearing and disappearing blocks and weird, Tetris-like shapes was a really cool concept and the gameplay felt pretty polished. One thing I have to mention though is that the controls felt a little unintuitive for me, constantly tried to press up for rotating and ended up messing up my game instead. Other than that it was a nice experience.
