Beat Block Practice Place (true BB challenge)

Sorry for the repetitive gameplay, although it was a practice place so i'm fine with it. Do you not like beat blocks, head to this for several practice areas involving beat blocks, including a challenge! The True Beat Block Challenge (aka TBBC or True BB Challenge) has arrived! No beat blocks were harmed in the making of this game. There are 4 sections, the 1st being a regular Beat Block section, the 2nd being a Beat Block section with wraparounds, the 3rd being a challenge that is memory-based, and the last being another challenge, but that is way harder, and more unforgiving, sitting at Terrifying/Catastrophic difficulty.
