It's a web app to help you improve your real-life pool (billiards) game. You can practice shots and learn to visualize the angles. Eventually, I want to go way beyond basic shotmaking and teach patterns, but it's already useful in it's current state at least to beginners and intermediate players.
I've posted about it before but I've made a lot more progress since then, including making it mobile-friendly.
I'm just aware that when you're playing you don't feel like you're moving in very fixed increments left/right when aiming, which using the keyboard seems to produce as an experience.
You'll only get the same results if you have exactly the same timing every time you tap the key.
That said, I've been prioritizing the touchscreen controls because that's where a majority of traffic comes from. I don't want to neglect desktop users entirely though!
Really like it over all :)
I've taken lessons with several instructors including a former world #1 player ( https://en.m.wikipedia.org/wiki/Mika_Immonen). He would make me get up and try again if I made the tiniest aim adjustment when down.
The "aiming" state is in fact when you're standing.
