Surprised at how much I liked this, well done! I'd totally play this on my phone if it had a bit more polish/content.
Love the balancing paddle, it feels physics based like you're drifting with it sort of. The aesthetics are great, some interesting screensavers/desktops etc. on the monitor would add a lot. Also more feedback for events, I didn't really realize when I lost a life for example and there was no visual feedback picking up coins except slight top bar movement. Music was enjoyable.
I made it all the way to endless mode. It's perfect gameplay wise for this jam, but long term I'd really like more randomness in the play (introduce special blocks for instance) or for it to get faster as the game goes on (could have chill mode and crazy mode even). I mostly chose second ball upgrade, and every time it spawned from top left which was a bit annoying depending on where I was - randomness there would be great too.
Overall, great work! If you do keep developing this and publish an Android version I'll play it for sure.
