is bottomless pit the final construction upgrade? if so, it seems like i've hit a wall where the only things i can upgrade are stats and that gets boring fast
Diamonds are ridiculously hard to obtain for like an hour or two, then something triggers the boss and then they just start raining from the sky. i usually have 1 or 2 diamonds by that point. It's 1 diamond for 1 billion coin
Tips from a gal you've probably never seen before:
Never level up critical unless it starts falling behind your other stats significantly, the mushroom gives you enough usually.
All stats (except critical) are pretty equal in importance, so just pick a build that fits how you like to play.
If you don't do training obsessively, you'll fall behind fast.
Always restock your potions and spells.
also whitefall is the hardest area because of the bullets blending in. I haven't gotten past it yet, so idk if it gets more dumb. it will get harder, I trust that.
the sad thing is, with enough time given I could actually wall-stall non-spoilery final boss's invincible form (some people are just playing this game now ok)
