Wow, what a fun and deceptively challenging game! I totally thought my love of the numpad would let me breeze right through, but I got tripped up real good on both songs, hah! Especially with skipped numbers, my fingers definitely got lost a few times.
Speaking of the songs, they're catchy and had me wanting to replay them right away! I think you really nailed having a simple concept result in a tight and really fun twist on the rhythm genre!! And, as always, love the font!
