I have a lot of high praise for this game, though, much of my feedback comes possibly in my Part 2 and 'Demo Finale' that'll come tomorrow, great work to the indie dev. Looking forward to the rest. Hope this gameplay pleases.
My feedback I'd say is, I think you should add 'Monster closeness' filters, static or whatnot - as well as make it perhaps uglier/spookier. Having static/grainy effects as he gets closer, but to make it not so 'clear' visually, as well as 'Because radiation' would probably help increase tension.
