Really impressive game! I love the style and it's a really unique take on rhythm games.
The controls seemed well thought out, I never felt lost on what keys to press since they have tactile bumps. I also appreciate having two keys for each hand for faster parts. The mapping always felt like it fit the song which is sometimes an issue with rhythm games. The gameplay got decently hard as well! I loved the songs especially that they were made for this jam, they had a nice variety too.
The text at the beginning adds loads of flavour but it made me unsure of what I was going into - like this might be a text heavy game. The instructions were great though, I loved the ascii art :)
I also noticed the timings only showed on the easy song - not sure if that was an intentional decision but even if you're playing hard songs it's really important to get feedback so you know what you're doing is right or wrong.
It's also a shame there's no thumbnail image since this game is easily one of the best looking games in the jam and really stands out.
Overall great game! Looking forward to what you make next :)
