Really liked this little game! Very cute and pretty fun. I like the art style a lot, and the music is good too! Also W yuri.
I did find the main gameplay mechanic to be a little too hard. It's very difficulty to tease out what I'm supposed to be doing with the mouse, and without your tutorial post, I would be totally lost. I did somehow figure it out eventually, but even then, I'm sill not sure what I did to get it right :shrug: I couldn't really find any patterns, and it felt more like a carpal tunnel syndrome simulator than a fun rhythm game after several minutes of struggling.
Ideally there'd be an in-game tutorial and a perhaps a difficulty setting, but you know what, for a free experience I can't complain too much! I'm just sharing my thoughts and experience of the game.
I don't know if you're gonna develop this anymore, whether you want to or can, but if you do, just know I would love to see this expanded! The concept here is really good IMO and just from this little demo, I can tell you've got the skill. I see a lot of potential!
But no pressure. I mainly just wanted to share my thoughts and let you know that I like the concept. If you decide to make more, I would be happy to see it. Otherwise no worries :)
