Great concept, and the aesthetic is really charming! I love how the paddles are greyed out to help you indicate where they'd be usually and to show you this isn't your typical game!
HOWEVER, I... feel very little impact on the board itself. As in, I left click and I have NO IDEA if I'm doing anything without any power up (Which I didn't even know existed in your game!). I feel like it lacks a bit of game feel on that aspect - which is really important. I also had tons of issues with actually getting the ball stuck, and that's something that you unfortunately lose a LOT by not having different paddles that you can send the ball in different angles - less aiming power. WHich is really important for a pinball. So you gotta ask yourself: Should I alter my main mechanic? OR accomodate my level design around that?
Good submission either way, nice!
