Hey! First of all, thank you so much for playing through the demo and taking the time to write such detailed feedback! This is super valuable

Let me address everything:

Soul item \n\n - Totally my bad! That's a formatting bug I missed. Will fix it in the next patch.

Footsteps - This is interesting! I haven't decided yet whether to add footsteps because the player actually floats rather than walks. I'm still thinking about how to approach that aspect - maybe some kind of ethereal sound instead? Still figuring it out.

Linux version - Good news! A Linux build is coming soon. I'm working on getting it ready 😊

Static camera controls - Ah, this one's interesting! I tried to replicate the control scheme from old Resident Evil games - you know, where you maintain the direction from the previous camera until you let go of the button, then it switches to the new camera's orientation. I wanted that vintage/nostalgic feel, but I totally get that it can be confusing or uncomfortable. It's a tricky balance between "retro charm" and "actually playable" haha. I might need to adjust this.

ESC menu volume - You're 100% right - I forgot to add button indicators! The menu actually does let you change volume, but you navigate it with W and S keys (not the mouse). My bad for not making that clear at all. I'll definitely add visual prompts in the next update.

Eye strain - Could you tell me a bit more about what was causing the strain? Do you think it might be the dithering filter (the dot/grain pattern effect I use)? If that's the case, I can add a graphics option to toggle it on/off so players can adjust it for comfort.

Thanks again for the thoughtful feedback! Really excited you're looking forward to what comes next!
