I tried giving this game a fair try but it's just not fun. The gameplay loop of finding things is done poorly. You can't do anything out of order. I find half the stuff on my own but then I have to backtrack and talk to NPCs to trigger item pick-up availability.
This click to move and item finding formula worked fine in Zombie's Lust (I assume LustZombie is inspired by that?) because it wasn't free-move 3D. It was tedious but not annoyingly so, because it had a limited amount of tiles I could interact with, since it was RPGM.
Anyway, I got up to the boxes puzzle, got all 3 of them stuck out of bounds and couldn't reset their positions.
