I've been playing Demo2-hotfix2, and I had a great time with it.
The weapons are good stuff, I liked the tracers on the automatic rifle shots because they let you know how much spread the gun has. The Trumpet Launcher's projectiles seem to be much faster than in Golden Souls 2, which is a very nice change.
As for visuals and atmosphere, what can i say, it seems to only ever get better in the Golden Souls series. Which means a lot. I noticed loads of really nice looking 3D models. Many of the music tracks are comfy to the point of making me sentimental, and you made Doomguy downright precious.
But the action in your mod gets the adrenaline pumping as well. I had some quite frantic fights in Serenity Shrine's lava castle. The long jump and wall jump make the game more interesting and varied, and getting armour from gibbed enemies is a really cool addition. Non-lethal pits were honestly such a good choice, they let me be much more daring with exploration and I almost never quicksave anymore.
There were a few oddities concerning the progression inside levels, weapon behaviour and movement though. I wonder if it would be possible for me to talk to you about these mechanics in more detail. This is all very interesting to me as I'm trying to get into the game design field in general.
Regardless, I'm really happy that you're making this mod. Thanks, and best of luck to you!
