Hmm, bit of a mixed bag that's a bit rough at the moment, but that is the point of a demo, so hopefully I can give some feedback to make it better!
*Overall I found the game to be pretty bland and lifeless in all aspects. The story was pretty drab and unexciting with no real big goal (though walking outside to see how desolate the world is was pretty neat), there was no animations or cutscenes which made events like dad falling down or the mayor running away confusing since they just vanish, there was barely any music or exciting sounds or effects, and the directions were pretty vague with no journal or anything to help keep track (don't get me wrong, I don't want a line or marker to follow as I like exploring, but sometimes it wasn't clear what's going on).
*There were plenty of typos and odd phrasing: felt like the script was badly translated from another language and could use a proof-reading pass.
*Controller controls were pretty bad: I had no idea how to navigate the inventory menu with the control and access other tabs. Felt like I was forced to use the mouse to access things like inventory tabs when everything should be possible with just controller. Perhaps it was because I'm using a Playstation controller: some games aren't built for it.
*I didn't even realize that I was being hurt when engaging in combat because, unlike the enemies which have good feedback to being hit by shaking and the slash mark effect, the player stands stock still and doesn't react. Even disregarding effects, though, combat was pretty boring and devoid of strategy (though it was kinda cool to get flashy kills when you level up enough to one-shot them).
*I felt like the whole way that enemies respawn when you reenter a screen was really annoying and punishing. I felt like the game could have a survival horror aspect to it where you really gotta plan whether fighting is worth it, but plenty of times I was forced to fight without knowing I'd end up going the wrong way, and it felt frustrating to go back and refight everything, especially considering I don't get exp from it. Just feels like it leaves too much up to trial and error and luck.
I certainly think that it has some interesting ideas and could shape up to become a grand adventure, so hopefully my feedback can help somewhat!
