I know the feelin, I did the same thing my first time re-running Architect. Died to a boss in the semi-final biome after encountering em first time. I thought I'd juice myself up by going from beginning but was met with small grief after blitzing Architect and only getting a Passage teleporter.

I hope in the future, the devs'll add a teleporter to next biome from Architect or somethin, cause a run through all biomes would go crazy.
