First of all, the hardest 2 player coop speedrun record we set was rejected, so I'll explain it.

i got a objection for your decision.

before i explain this i have to write about rank system.

the rank system is auto difficulty adjuster (or it called dynamic difficulty adjustment).

it isn't shown in game screen but it keep increasing when you are not dying or complete stage.

when the rank is high the enemy hp will be increased, player hit damage will be increased.

the reason for brenda hp gauge not showing green is that

we killed stage 1 boss too fast by using bug then we meet the brenda in stage 2.

since rank system is NOT HIGHLY ENOUGH to show green hp gauge

the brenda hp gauge show yellow.

if you still can't understand what am i saying then keep dying as much as possible. then meet the brenda.

you will understand what is the rank system it is.

1. 'Not' Use Bug kill Stage 1 boss and next stage 2 brenda engergy bar(top video)

2.'Use' Bug kill Stage 1 boss and next stage 2 brenda energy bar(bottom video)

I don't understand the rules well, but the first level must start with an ice planet unconditionally?
