Holy moly what detailed feedback, thank you!
I actually was hoping that the multiplier (which, to be fair, is not explained in the game at all) would discourage button mashing. In fact, from your strat, it seems to have done the exact opposite lmao. I didn't want the timing to feel too unfair, so that anyone would feel at least a little satisfied after playing. I may have gone too far in the other direction. I'll need to rethink either how the multiplier works or make the off-screen distance less forgiving.
I hear you on some of the controls being used. I considered starting off right away with bouncing, but wanted to give players a place to practice and ramp up before the real game started. Again, this stemmed from anxiety from not trusting the player, and I agree there could have been a better way to use some of the rarely used inputs.
The score displaying wrong, yeah, it's essentially counting up way too slowly. With how quickly the score can go up with the multiplier, it takes forever to pace and catch up with the final score. It's really a quick fix, but one I didn't get around to in my rush before the deadline.
I'm glad the game was still fun to play! Appreciate your input once again.
