I enjoyed the game a lot. It's like a nice pared-down Resident Evil style horror game. I finished with one health left and no healing items remaining. That was a bit tense.
*potential spoilers below*
I had to reload the game a couple times on the last hallway full of monsters and barely had enough ammo to finish them while I had one health point left. Thankfully I still had some ammo because I ran away from the monsters in the shotgun room instead of fighting them.
I probably would have liked a bit more margin for error with maybe at least one more healing item and ammo but I made it through so maybe it's fine.
It would be cool if there were some hidden supplies the player could find. (Maybe there are and I just never found them!)
