The retro style worked well, except for the immense eyestrain after playing few minutes on full screen :/ I think if the lines were little more thick or somewhat transparent it would be better, but regardless: The game worked well and I must say sound design even if minimal was nice. Levels did start to feel a bit repetitive towards the end of the game, so if there is further development I'd recommend adding more visuals to differentiate each area and make it easier to navigate. Oh I do suppose it could add tension if the bigfoot in question would make more noises!
Overall, I liked the effects and the overall aesthetics were fitting. Good work.
