33 was my high score! I can see this being a fun game to expand on. I like the idea that it's not height, but bounces that adds to your score. You can try to box the ball in but if an object isn't the right size, you might trap the ball or knock it away instead.
I believe the game would benefit from an outline of the object you're about to place, and the Tetris Hold/Next UI element. Being able to see what block comes next could add an element of forward thinking, rather than how it goes now with spamming left-click to box things in or trying to play pong with the ball as it leaves the screen.
Also, it might be more clean to have the game end when the ball exits the screen horizontally, instead of just vertically. Sometimes the ball would leave the screen and I'd have to sit there doing nothing for a few seconds before the game marked itself as over.
Y'all should definitely work on this more because it feels like a classic browser game! High score, silly physics, easy to retry. I probably don't have to tell y'all that I wasn't feeling the theme in this one, but then again, I did anticipate a lot of folks interpreting "loop" as "game loop". Still had my fun with it all the same :)
