I loved this entry *-*
Well, I love pinball games in general, but it was refreshing to see such a clever twist on the genre: the mechanic of having two types of balls - one good one bad - is a great idea with a lot of potential. Added to the fact that the balls can be more than two, that they have different levels of power, and they are purchased from a market, it makes the gameplay so interesting and solid.
On the other side, the quirky horizontal movement of the levers felt almost unnecessary: the other mechanics were already innovative enough. The controls also seemed a bit laggy, but I know it's hard to make everything work smoothly in a short-time period game jam, so don't worry.
I think you did an amazing job! Congratulations, I had a lot of fun playing this :D
