Beat-based games must have good music, and I'm glad to say that this game's soundtrack is groovy! Controls could be a bit tighter as the blue ball felt a bit heavy to move around sometimes, but solid concept with solid visuals!
The speed of the blue ball is capped so it deasn't make the red one fly everywhere too much (as can be seen in the menu where the speed is higher). Though it's definetly something to balance out.
