First of all, Hi everyone. I've been lurking around the forums for some time and finally decided to register here. While I am no pro at all in terms of Tetris and/or TGM, the series fascinated me since that famour Death 800 video. Though I used MAME to play TGM and TAP, I got the ... PC dump of Ti last year. If I ever hit Japan some day, I'd sure really like to check out the real thing in an arcade of course. While not being the real thing, at least I am happy to play that awesome game Now I'd like to know two specific things I didn't find any useful info or simply used the wrong search terms (Google and tetrisconcept as well). 1.) How does the falling speed increase work with user accounts in Ti? The wiki says it changes depending on your skill, but does this "skill" only covers your current game (I may think number of tetrises, block placement, no holes etc.) or also is affected by your long-term progess from your last few games, like exams take into account? I mean, I am not that good, so in Master the game slows down at lv 300 (like its TGM and TAP always do), to speed up again, eventuelly hitting 20G at lv 500 for me, if I get that far however. Lately it doesn't slow down at lv 300, but continues increasing, sometimes in resulting in change of background/music at lv 400 (no 20G though then). Does it mean I simply am faster than a specific hidden time to make the game think "Oh, that player is not THAT bad anymore, let's tack the speed on a bit more!"? Or does it even account the previous playthroughs, I usually end up only at 4 or 3 grade, rarely 2. Often hitting the lv 500 torikan, recently made it with FIVE seconds to spare 2.) Sometimes I see little sparks or little ... meteors (?) floating down diagonally in Master mode. It often happens when the game ends, sometimes in-game, I saw up to three of them flying around. I always forget a screenshot or am simply too slow to do it. Is that kind of indication you did good or bad in a section/your overall skill progess? Hope I put up those question in an understandable way. Thanks for your answers.
