I'm gonna be honest
The game's ok. It has alot of issues holding it back, though.
The automatic generation for music to let it go on endlessly isn't the best at making it feel on-beat. The slow down/speed up mechanic is game-ending at the worst of times due to the difference in beat speed--- distracting at best. It ruins the flow of the song and comes out of nowhere, not like there's much of a rhyme or a reason for the beat placement.
The control scheme is awful-feeling to me, that being the arrow keys--- And no way the rebind the controls. I understand alot of people are comfortable with using the arrow keys, but... I feel like being able to customize the inputs would add alot of comfort to the game.
There can be better than this game, but there's definitely worse rhythm games. This has alot of potential, if it's worked on.
