thanks so much for the feedback. I meant to remove the only one upgrade between runs limit. I initially added that in as an effort to prevent users from hoarding but I think that the limit gets the job done, so yes I plan to remove it.
My plan for the last sprint was to add as much as possible to tie in the story so I'm glad you enjoyed the additions.
I think the issues with loading the biomes is either coming from a threading issue or how godot handles making so many changes to the tilemap between the start up frames. I think I may have to change my strategy for map generation as I wanted the player to have the option to leave rooms without having to clear out all the enemies mainly so my husband and kids could enjoy the game without it being to punishing. I may have to change to more of a load a room at a time approach to improve the stability of the game.
