I actually started this to be a pinball layout and was collecting assets for that but it worked out much better as a standalone bowling game.

I am using simplified scoring for now plus a cash bonus if you hit a randomly selected pin in any frame. I plan to add other bonuses for trick shots as I progress.
This plays very well and it requires some skill and practice to get the ball right where you want it on the pins and moving the player and changing ball speeds and curves has a big effect on where the ball goes.
This is still bare bones and the controls and scoring etc. will all be made better in updates.
So go give it a try and tell me what you think and ideas for bonuses to make it more interesting appreciated!
