Real G's move in silence
All right so I should try and beat the boss with as much upgrades as possible since they will carry over? Why when I die, I lose it all? I noticed the traits stay
I don't want to spoil it but each biome has a permanent equipment upgrade that can be used if you die and have to start over. There are new weapons the further you make it and once you get them the first time, they can show up in the 1st biome from then on. A good strategy is to clear the whole first level and don't move onto the 2nd until you've gone in all the rooms of the first. You just want to be as prepared as possible.
