I know its nothing special to you, but I greatly improved my 20G yesterday: 664 @ 10:31:20 My best game so far was around 350, so to me this single game means going to level 999 in a regular game is indeed possible for me.
628 - S4 6:XX My first time doing 500+ levels in 20G. Turns out I CAN do it! Wasn't fast enough to grab a screen shot (PCB )
799 - S7 (no clue on the time), KB Trying to up my 20G game so I can GM more consistently. Had a totally clean stack up through 6xx, which was rad. EDIT: 999, S9, 12:45:71. Just missed S4 at 500, so no 20G GM for me
I'm grinding 20G in my efforts to become a TGM1 Gm. Sorry couldn't get to my camera phone as fast: Grade 2 - Level 323 - 3 minutes or so?
I decided to drop back to TGM after spending quite a bit of time in TAP and after not a lot of success in the low gravity I decided to just play a 20g game. I didn't grab a picture of the 20g code sorry, I wasn't expecting to do particularly well. This is also my first clear, so I'm a little bit salty that it was using a code and isn't recorded anywhere but here. This is on MAME in case it matters.
Didn't have my recording stuff running because I didn't expect this to happen (but isn't that when it always does?) So I had to snap a pic. First 20g clear!
That's a fast time for 855 but a low score, you should try to play slowly so you can have more time to secure tetrises and triples (which will, in the end, get you a better time)
