good art and interesting premise, but I feel that it truly would have been better if the main character were human, the main character actually being a wolf or dog or whatever doesn't really add to the horror, in fact I would go so far as to say it takes away from it. some of the best horror is good because our mind can find something to relate to or latch on to, so if we feel that we as a human are being treated like dogs we feel mistreated or demeaned, but if we feel that we ARE dogs and are being treated as such we feel prideful, also just the fact that the MC is a dog could be a good artistic choice, but only for like an intro, and don't make it seem like a fanfic, this is a horror game and shouldn't be taken so lightly. the monster design was great btw.
I should also say that I'm not trying to be mean, I think you are very talented and this has huge potential, also not saying you need to rewrite your whole game or anything, just trying to give some pointers if you're open to them.
