I tried my best to recreate a QR code that everyone could scan, but wasn't able to do so. I'd really appreciate it if someone of superior rank (which means anyone compared to a novice like me) could lend a hand with that issue I'd be extremely grateful!
Enjoyable though first ball mechanism jammed first time and large ball-triggered rotatable sprung up by itself next try.
Didn't notice anything others haven't already mentioned. There must be a LOT of free moving stuff going on under the covers, because my app was lagging, but it was still playable.
