This is a fun puzzle game! The sound and ambience is solid; the music conveys the timing excellently. The mechanic is enjoyable.
I will say, however, that I found the levels extremely difficult to execute. Some of the timings are really tight! It feels like even after finding a correct solution, executing it is on a split-second timetable. I feel like that could be eased up a bit.
All-in-all, superb! Great work!
