Much appreciated and it makes me feel less bad about my video gaming skills to know the game is intentionally kaizo tier difficult. I can respect the decision thus to not have an ammo counter nor crosshair for the sake of intentionally immersive difficulty. The gameplay advice is helpful and I will be attempting to progress further naturally with it!
I do appreciate the 'cheat' to skip the levels that are to difficult to beat get to the yaoi VN portions!
