Okay, so, I played this for about an hour and I want to discuss how I felt about it.
First off, let's start with the good points.
The game's pixel art and visuals are amazing. I adore the aesthetic of the game in both the design and animation. I cannot express this enough, the game is Beautiful. The visual style alone really made me want to praise this game so much more. Also, the songs are fun to listen too, I caught myself sitting in the menu vibing out to the simple menu BGM the entire time writing this.
However, that is about the most good I can say about the games design. Let's discuss the gameplay.
I want to start off by saying that I hope all my critisism comes off as 100% constructive and I do not mean to bash the developer, mearly express my thoughts.
The game is excessively difficult, to the point of me genuinely feeling like nearly 99.9% of players wouldn't be likely to complete a single song in the list without having the No-Fail or "Apprentice" setting active.
Everything that the gameplay relies on goes directly ageinst most all relfexes and common sense that a rhythm gamer relies on. Most every obsticle needs to be avoided off-beat rather then on-beat. You cannot see nearly enough of the track to feasibly know what is coming before it is too late. Jumping over the jump notes needs to be done Before the note actually reaches you, rather then on-beat. All of these things result is a very nearly impossible to complete, and overwhelmingly frustrating experiance for rhythm game fans.
The last thing I must add is about the controls. The game's controls aren't nearly responsive enough to keep up with half of what you're trying to do. Ive noticed many many many times where I would do an input, get hit, and have that input persist after the hit and then activate, causing me to get hit again. This would continue until whatever section I was in was over. The Z/X input of the game is fine, but you really need to be able to rebind the left/right movement off of LeftArrow/RightArrow as having to spread your fingers for those two inputs in uncomfortable.
TL/DR: The visuals and music are awesome, but the gameplay needs a HEAVY rework to be even remotely completable without the no-fail mode active. I can see the passion put into this game and want to love it, but its just too frustrating of an experiance.
