Pretty addicting; pretty challenging; pretty awarding game this one! And such a unique idea too. Love the design, and especially the layouts that start appearing after the 20th, feels like it'd be possible to take this all so much further after those! Bigger levels, arrays of speed-up arrows and obstacles, faster pace for more important reaction times...
This was a blast to play. Was stuck on level 19 for an aggravatingly long time but other than that the difficulty curve feels just right too.
