What is this, a mobile game?

You created this perfect progression system with lots of stats and upgrades to grind for, and you ruined it with this one tactic. You can only buy things if you have one really good run instead of running a few good times and progressively working towards something. This is something I'd expect from a mobile game but not this.

wait how does rogue legacy work then
is it multiple runs that you play through or smth

You do a run and get money. You then spend that on upgrades and then you have up give up the rest of it to run again instead of being able to save up.

oh

*have to give up
