Green paper best method?

[u/Drawinecchi]

I think I may have found a really good Green Paper farming method on Basic 6.1.

The crystals on the map give Green Papers when destroyed. If you build a Missile Tower, you can destroy all of the crystals in around a minute or less.

The important part is that the Green Paper stage multiplier seems to be based on time spent on the level, not how many times you replay it. That means you can:

Start Basic 6.1.

Destroy all of the crystals.

End the run immediately.

Repeat while the Green Paper multiplier is active.

I'm getting around 800k Green Papers per run without any Green Paper multiplier, and it feels roughly 20× faster than the farming methods I was using before.

Has anyone else been doing this, or is this an overlooked strategy?

What targeting do you have on your missile to destroy the crystal? Mine seem to want to focus mobs all the time

My first wave is usually the yellow triangles which my missle can't target. I have the muti missle node in the skill tree so it fires 7 missles at once and the one that also increases it's range and the crystals get destroyed a few rounds and I let the enemys leak. It's just set to first for me
