Hmm, bit mixed on this one!
For the most part, I think the game is pretty cool! The retro ZX Spectrum aesthetic is very neato, the town is huge with all sorts of interesting environmental details, there are a lot of creepy aspects to the game which are both subtle (faces appearing) and overt (monster chasing you, descending into hell, etc), there's some amusing little touches like recognizing my attempt to run the monster over with a car, and so on and so forth. It's also rather amusing to read the whole backstory behind it to get in the proper mood. It's just got a very cool sense of mystique to it all!
However, in retrospect, I think I like the game more in theory than I actually enjoy playing it, if that makes any sense. It's like, the game gives off cool and mysterious vibes, but when it comes down to actually playing it, I'm an ending 3 kinda guy: I just can't be arsed to search through this absolutely massive town to find that dog, especially once you get the monster nipping at your heels and you just can't lose him no matter what clever tricks I try to use: from there, the monster just devolves into white noise, kind of like the missile alert sound in an Ace Combat game.
To add to that, there were some aspects that felt a bit rough or unfinished. For example, I found these books lying around which I assume are secret lore or something, but I can't interact with them: maybe they can only be interacted with by winners who have rescued the dog at least once? I was also unsure whether the ability to cheese the monster by abusing the non-normalized movement vectors which make diagonal movement much quicker was intentional to represent the old-school construction or an overlooked aspect. And the creepy faces seem to be all that happens, when I was expecting more interesting scares and distortions to build up over time to make it all creepypasta-like.
So yeah, in a way, it's the old style-over-substance that I'm getting from this game, but I still think the game is pretty neat and can excuse some of the gameplay quirks because it is trying to authentically recreate retro limitations and such. Definitely shows a lot of promise and effort!
