Not bad! It was fun.
The flamer's projectiles are a bit slow considering how fast you run, maybe they could inherit the player's speed?
The shotgun felt great, the tommy gun less so because imo the generic grunts are a little bit too spongy.
Not that it was too hard or anything, but it was a little annoying having to wail on them with the pistol.
I noticed bullets go through them so they feel less spongy when they're clustered together.
The only other annoying part was fighting around ladders.
The boxy 3D environment clashes a little bit with the sprites, but the weird scale is more distracting: the environment is way too big in relation to the enemies and the player.
Especially noticeable with the stairs being so steep and the toilet stalls being gigantic. This is more of an issue in the first level, the second one looks better imo.
The first level had the exit open from the start which I think it's a bug because the green key doesn't open anything as far as I can tell.
The second level had those cool scripted sequences like the cars unloading grunts and the tram, but it was a bit dispersive, it took me a while to find the green key and the sewers and until I did it felt like I was wandering around aimlessly killing grunts instead of progressing somewhere.
Just a me thing tbh, I prefer boomer shooter levels to be a bit more focused.
Also the dark parts are too dark, like in the underwater section of the sewer it was hard to see anything idk if I missed a torch feature or something like that.
But yeah it was a fun demo.
It doesn't really have any uniqueness when it comes to enemies and weapons, but I guess it's just the early levels so it's forgivable.
Will definitely play more next DD!
