I've waited for half a month. Finally, Mars's has been published...

This movie improved 121 frames.


  • Pacifist (Do not kill an enemy which can be avoided)
  • 2 players run
  • Uses death to save time
  • Luck manipulation

About improvement

  • Area 3: 11 frames ahead.
    • Before boss appears, I saved 2 frames. 2 jumps saved 1 frame each time. But area 3's and area 5's bosses appear in every 8 frames (8 framerule). And Mars608 used full framerule in previous run. So I used a pause in area 2. It cost 2 frames to instead of 2 lags. So the 2 frames saved.
    • Better boss fight. And 11 lags avoided.
  • Area 4: 1 frames ahead.
It's saved in boss fight.
  • Area 5: 52 frames ahead.
Died earlier at 2nd tank. And P1 rebirth when he can shoot boss.
  • Area 6: 2 frames lost.
Due to 2 more pause. But I win 2 frames by the better Y subpixel.
  • Area 7: 1 frame lost.
To wait P2's death. But better Y subpixel and fewer pause saves some time.
  • Area 8: 60 frames ahead.
Because 2 players don't have S gun. Bosses have lower HP.



  • 和平主义(不杀死任何一个可以避免的敌人)
  • 双人
  • 利用死亡节约时间
  • 运气操控


  • 第3关: 提升11帧。
    • 关口出现之前提升2帧。有两次跳跃,每次快了1帧。但第3关和第5关的关口的出现时间相隔8帧(8帧规则),而且Mars608把8帧规则用满了,所以我在第2关用了暂停,即2帧游戏内时间替代2帧实际时间。所以第3关关口提前2帧出现。
    • 更好的boss杀,避免了11帧lag。
  • 第4关:提升1帧。
  • 第5关:提升52帧。
  • 第6关:落后2帧。
  • 第7关:落后1帧。
  • 第8关:提升60帧。

Masterjun: Judging.

Masterjun: Waiting half a month before accepting, in case someone improves this submission.

Masterjun: Okay, doesn't seem like it. Accepting to Moons as an improvement to the previous run.

Spikestuff: I'm going to turn around to another submission after this.
