Okay, so the beginning is pretty good. But when I got the bottle with the key in it, I tried to throw it and it fell to the ground. The key was gone... However, I feel like the monster in the beginning came too early; that may be just my personal opinion though. Next; the corridor. I think its a bit too claustrophobic. Make it a little longer and add paintings or windows, or place boxes to make it seem more "alive". I opened the door and theres a small room with a random pit in it. You gotta work on that
Anyways, I have no complains about the water part, except WHY, WHY a flying naked guy. It wasn't scary and it ruined it a bit for me. Okay, now that's over, onto the next part, the "morgue"-like part. I think this room is the best one out of all, especially when the grunt bashed the second door open in the bloodred-colored water room, where I was hiding and crying in the corner. However, the brute right after that was unnecessary. And I couldn't get into the other room in this part, I didn't have the key (see beginning). And when I Hammer-and-chipped the lock, the door didn't lead to a new .map file. So that's the end I guess.
TL;DR bit too many monsters, this makes it feel too rushed. Make the rooms bigger and add more detail and non-purpose rooms (rooms just for detail). Overall not bad. Lack of story. Overlapping textures. I
loved the flashbacks. Even though there were from the original games. And theres no .lang file it seems? But I'd say keep working on it! This has lots of potential!
