Isaac Items, Shops, and Devil Deals
How to spend keys, when to bomb, and when a deal is actually a wipe.
Treasure vs shop
Early keys usually go to treasure rooms. Shops matter when you need a heart or a bomb to open a secret.
Devil/angel
Angel chance is a playstyle. If you already donated red hearts, commit. Mixed deals often leave you with nothing.
Synergy thinking
Tears, damage, and a way to not die. Homing on 0.9 tears is still slow.
Alt path
Downpour and mirrors wait until you can spare health. They are extra unlocks, not a mandatory tutorial.
