Yeah there was a lot of bugs unfortunately. The barrier upgrade came around because my main playtester was my girlfriend, who got ALOT of gutterballs, which made me think it would be more helpful than it probably is. The split upgrade was a pretty late addition and was programmed to take the physics velocity of the ball that already rolling, but yeah clearly something went wrong with it.
The biggest bug, was the vending machine not resetting. This was supposed to reset to zero after each 10 rounds, meaning like each game you could get a different set of the random upgrades and actually give it that rogue-like randomness. Because that didn't work it just becomes like a flat power curve with the upgrades and you run out of stuff to buy pretty quick.
Either way, thank a lot for playing, and I really appreciate the feedback.
