I do agree on a lot of errors you pointed out. The limited resources were based around critical hits and enemy types. Saving ammo could be done in multiple ways
Basic doll = one head shot is a kill
Pig heads = are slow so the axe is made for fighting them using the block
Ceiling doll = is just one hit from melee
On first pickup of ammo and health all past locations in the game (sides rooms and so on) now have resources and extra ammo
The game was made with the idea of taking on encounters when they showed up.
Either way thank you for your feedback and I'll use this info for the future and thank you for playing once again.
