I love the concept, but the execution isn't quite there yet.
Would be nice to have a preview of value while starting the hit. Needs a better color scheme because it's hard to differentiate the ball types at all until you get the weird ones. I would prefer realistic sounds due to how much more satisfying they are.
Some balls felt heavy despite not having it in their description. Hitting balls didn't feel accurate (as in push direction when hitting off center didn't seem realistic), but that might be me.
The background together with the white ball slightly rolling constantly creates a nauseating feeling.
Sometime it seemed like it bugged out and billiard cue wouldn't start hitting at all. It also would be good to have a visual hint that you are starting hitting and the power should be conveyed better too. At some cursor positions the cue spazzes out completely.
I'm not sure about the score threshold and shot count limit due to how rng heavy it is, but I guess it is a roguelite. It could have some partial losses and additional reward conditions. I got to the final round but probably by sheer luck.
