not sure if this is intended but once I get a game over upon pressing either buttons presented I get an error and have to refresh the page to play again.
I also agree with another review that a tutorial or at least some controls listed in the description would be nice.
Besides this though the game is fairly interesting and pretty entertaining trying to see how I can get this damn monster off my back lol.
Edit: Okay so I think I've figured it out you have to find the pistas while hiding in bushes to not be seen. (also the monster can still find you in the bush if you're unlucky and he bumps into you or if music is already playing in which hiding will not save you.)
This is pretty tough since in some areas where there are pistas there are a lack of bushes to hide in so if you're seen its over. I recommend sprinting whenever you're not near a bush otherwise save the sprint. I'm not entirely sure if there is an ending to this game once you find all the pistas I've only managed to get 3 before dying, Knowing the amount you have to get before going to get them would be nice because that way you would know how close you are to the end if there is one.
Overall a very nice game that is fairly similar to slenderman.
