I like the idea, it's pretty fun to play, My only draw is there's no audio, but other than that, it's pretty cool!

As Wembo also said, adding a bit more visuals would also be nice.

Nice job finishing your first game! The time crunch was real, so I understand that you probably didn't get to playtest as much as you would have liked to. But if you're looking for feedback, I would say that pinball machine games are a bit like casino slots, the controls are simple, but people are engaged by the constant visual stimulation that happens on screen. Maybe adding more visual effects and emphasis when the pinball interacts with different point-scoring elements would help maintain player attention span.  I would also add a one-way gate so that the pinball can't fall back into the launch zone ;) But I liked the moody atmosphere of the last level, would be cool to lean into that and make the whole thing ominous and creepy, def adds to the serious meter.
