Because of the busy work, my friends and I can't continue this WIP anymore.
But we don't think it's necessary to use two-role bugs at all.
Because double-role bugs can lead to other unknown consequences，I already know where not refresh is.Some ideas about these not refresh locations：
01.Stage 3 here, killing a player can achieve not refresh(Here are three Spearmen，Continued to three white knife soldiers)
02.Stage 3 here,killing a player can achieve not refresh(Go straight to the boss)
03. Stage 4 and Stage 5 are normal checkpoints, and there will be no non-refresh positions.(That's why we believe that maintaining a character's hatred can help improve the efficiency of killing boss.)
04.stage 6 here，killing a player can achieve not refresh(But it doesn't affect the speed of the rollers here. It doesn't matter if it doesn't die here.)
05.stage 7 here，killing a player can achieve not refresh(Phase 7 has a trade-off,If you kill a player beforehand, there won't be no refresh.)
06.stage 7 here，killing a player can achieve not refresh(Phase 7 has a trade-off,If you kill a player beforehand, there won't be no refresh.)
07.stage 7 here，killing a player can achieve not refresh(Phase 7 has a trade-off,If you kill a player beforehand, there won't be no refresh.)
08.stage 7 here，killing a player can achieve not refresh(If you kill a player beforehand, there won't be no refresh.Go straight to the boss)
09.Stage 8 are normal checkpoints,and there will be no non-refresh positions.
10.Overall, I recommend maintaining a character's hatred.Because if two role bugs are used，There will be bugs that can't continue the game.
Here, for example, if two role bugs were used, the two soldiers would never appear.There are many similar consequences.I'm just illustrating one.
summary，If a team or individual wants to continue to complete the WIP，Some more techniques:
1.The oblique movement of the character is faster than the lateral movement.
2.Raph is the quickest way to deal with ordinary enemies.
3.Try not to achieve life-rewarding scores when killing boss(Because of the sound effect, the sound effect has a delay of 40 frames.)
4.Control the flying altitude of raph in killing enemy.
5.Krang and super shredder, it's better to Don and Mike.
We are confident that we can push the completion time to 27-28 minutes.Unfortunately, the work is too busy.
This is the starting frame of dasrik's
This is the end frame of dasrik's
7566-691=6875
This is my starting frame.
This is my end frame.
7524-555=6969
6969-6875=94
so,i'm 94 frames behind him.There may be two factors,at the end,i had five more lag frames than him.and he chose Mike to join the boss battle.
