Hi, thanks for the really detailed feedback. Completely agree with your thoughts on how the difficulty of the monster progresses, getting everything working took longer than planned so unfortunately I didn't have as much time as I'd have liked to put into balancing the game to make it more challenging/scary. Planning to revisit the game at some point and have a few ideas for this. Was thinking of maybe preventing running whilst using the giger counter or making it so the player needs to take medication to keep their radiation exposure down, which would force the player to slow down periodically. Also, your ideas about ammo being a bigger factor are great too. Ideally I would also like to move away from the 'slender-esque' gameplay loop too, maybe taking the game in more of a survival horror direction where the player has more elaborate objectives and more things to focus on.
Thanks again for the feedback though, very helpful stuff :)
