I started playing Nullpomino's Grade Mania Mode and I am stuck getting near 20G gameplay. At some point I don't realize I cannot move or rotate a piece to the place I want it to be and most of the time I misdrop the next pieces afterwards too. I already read some guides (for example http://kitaru.1101b.com/TGMGUIDE/) or the wiki here so I roughly know about the theory, but 0.5s are not yet enough to act according to theory. Is there a recommendation how to get better at 20G? Should I just play normally or with 20G mode enabled and be patient until it happens naturally? Also can you recommend another Tetris with TGM style rules for PC? I read the emulation of TGM1 (video bugs) and TGM2 (runs too slow) is broken.
