Considering there's a "Normal Mode" and no other modes, along with the fact that the force the bottom sets of paddles/bumpers are WAY higher than the upper board, I imagine this isn't actually the "Final" version.
Also, the ball gets stuck often. Sometimes it also goes fast enough that it glitches through solid surfaces. The game has big lag spikes when the girls load in. Most annoyingly: whenever you get a match on the slots, it zooms into the girl (even if it doesn't change something there), and HALTS the ball movement entirely, and when it is done the ball just flops straight downward. Considering the placement of the slots, this causes the ball to just fall right down between the paddles 9 times out of 10 when hitting the center slot.
