Nice work Dan! I know you were dissapointed with the file size, but I expect with a bit more time you could have optimized it down to under 32.
I do like the music and sfx elements, it really adds to the oldschool vibe.
I killed Fisher a good few times though! A few nice random elements like the item placement. But I had a few games that seemed unwinnable. Maybe Im missing some mechanic, but one the alien sat itself in a I needed to get through I couldnt find a solution. But either way, I like the vibe of the game, it certainly seems like an interesting horror/puzzel game, nice work :)
