I suggest to modify the rule that the players should not use existing saved data. The reason is that it makes shorter the running time. It may enable to skip "NEW RECORD" showing time.

Here's the related games' rule. Super Tetris 2 + Bombliss: Prohibited Tetris 2 + Bombliss: Not mentioned

I understand your explain. But, how can we identify the RNG manipulation? I thought it was difficult to specify whether the RNG manipulation was used or not.

Thanks for your rapid response! I appreciate it.

This movie is my play. In the following movie, the score name is HBM and matches my play. https://www.speedrun.com/tetris_web/run/mr4x0p4z

Here's my original movie.

Thanks.

The rule said the following text.

Complete all rounds and stages. This includes all levels from 1-9 with all rounds of 0-5.

However, this mode has 10 stages (0-9) and 6 rounds (0-5). So, I suggest to modify the rule below.

Complete all rounds and stages. This includes all rounds from 0-9 with all rounds of 0-5.

Thanks.

Each category rule is the following: Real time; starts on selecting Area 1 and ends on 90th line of Metamorphosis.

Area 1 has 3 stages and the rule is ambiguous. I think that the rule should be written this: Real time; starts on selecting Area 1 "The Deep" and ends on 90th line of Metamorphosis.

Okay. I see. I think there is a difference whether the game is cleared or not, between those two categories. I think those categories are necessary. But I agree that both are for an expert. I'll hear other players' opinions.

I will play for run this game near the future. This game has lvl 30 and can clear 300 lines. I wondered that 300 Lines category did not exist. Why don't you create the category: 300 Lines? Thanks.

(added) Here's the sample movie. Actually, this movie is not about this game but related to this game.

I have a suggestion to separate the records of GBA console from others.

I have 2 reasons. At first, GBA version has smaller width of field. This makes faster than other consoles.

GBA : 7 cells width Other consoles : 8 cells width (*Edited)

At second, GBA version has no loading time.

How do you think about this?
