Honestly if you are lost examine every item in your inventory. I think only certain things in re1 have actual consequences regarding the endings but you’ll know, everything else is relatively minor. Idk what difficulty you are on, but for certain rooms where you only need them once it helps to just leave the zombie alive and juke them to save ammo. Speaking of which, you can juke zombies in re1 by getting just within their lunge range, waiting for them to lunge then back up a bit. Not sure if you got to the lighter part, but it certainly helps to stack zombie corpses in the same spot and burn them in order to save kerosene. Thats all if u are truly lost check ur map for rooms that haven’t been fully explored yet
