Really awesome idea, the powerups are all really fun to use (except the portal gun, which is way too hard to use in the jam version) and I had a great time overall trying to beat my previous scores. I also liked the music and the artstyle.
The ball frequently getting stuck is kinda annoying though, I'd suggest adding something like a way to nudge the table like on real flippers (and potentially get a tilt if you abuse it) to try to compensate the issue, though I don't know if this would go too much against the core design of replacing traditional flipper mechanics. Also I saw that you posted a post-jam version of the game, but unfortunately I can't get it to load on my machine.
Still congratulations on your fantastic work, had quite a lot of fun with this game, and I think it has a lot of potential if you ever decide to expand it further.
