I'm gonna state that I am a rhythm gamer so I'm going to be excessively picky.
1 of the core components of a rhythm game, the "gimmick", was done very well e.g. I liked how 1 is a double tap in any direction. I’ve played a lot of rhythm games and this is the first time I’ve played something like this. If I had to describe this it would be some sort of crossover between Rhythm Doctor and Stepmania (but even then, it doesn’t even come close to the concept of this game). Massive kudos to creativity and design.
Charting and music are 2 of the 3 the core components of a rhythm game. The music is decent and good, not particularly outstanding, but given the time frame, it is understandable.
Charting was my biggest problem imo. The fact of a very simple rhythm 4/4 each beat made it very mundane.
I also felt the scroll speed had some sort of rubato to it (is it a choice to prevent the mundanity of a simple rhythm)??? Like it kept on speeding up and slowing down. I don't know if this was on purpose, but in the end it didn't sync well with the music. There is also a lack of good audiovisual feedback (e.g. sfx when you make click/tap, early/late indicators, different sfx that play when you get a good vs perfect timing, lack of timing window): putting perfect on there is just the bare minimum.
Overall, a good solid attempt at a rhythm game.
