Bug out
this one is easy kinda
just beat it normally and you will get around 30k
but beat it without dying and get a perfect you should get around 100k

waste in space

this one is hard and sucks but it gives alot of money

play it normally up to stage 4
on stage 4 pick up all the trash expect for one
once you have all the trash in go grab the last one
now leave it near the space ship








should look like this^
now die and when you respawn grab it as fast as you can and bring it into the ship
doing this should give you 97k but i have seen some people even getting up to 150k

This is all the ways i know to get good money
if you know anymore leave a comment and ill look into it
thanks for checking this guide out.
