As other mentioned, the neutral's were confusing. At the end, no matter how good you are doing it, it seems a matter of time that you lose due to accumulating neutrals. It would have been nice to give them a way to be destroyed, maybe as normal tetris and getting a line of them to get them rid of?
I twist on the classic and the idea of the storm, even if sometimes I was getting a 4 line of either + or - and I was forced to put it horizontally to avoid the consequences hahaha
