[antimatter dimensions] what should i spend infinity on

I dunno, I stopped playing years ago

all the upgrades in the left two columns, then all the upgrades in the third column

then alternatingly fourth column and autobuyer upgrades

early in infinity, Challenge 8 is actually faster than doing normal runs

for the first... 6 or so IP

I actually finished a Challenge 8 run lol

keep running 'em
