I like the setting and the realistic atmosphere.
I am fairly experienced with stealth games but I wasn't able to complete the 1st objective. Tried for about 40 minutes. It seemed like crawling all the way across the town might have worked but I didn't have the patience for it.
The stamina system is the big problem. It's extremely frustrating and makes any detection an instant death. Escaping an alert is already hard enough because areas are mostly wide open with little cover. But running out of stamina in 5 seconds and then slow-walking away from enemies shooting you feels terrible. I don't think there is a need for any stamina at all -- sprinting is already balanced out by making you very visible.
Enemies can see very far and they enter alert almost instantly, even when the player is crawling, on default Easy difficulty.
The amount of time required to hold ctrl to get to crawl is way too long. Makes it feel very clunky, and not useful as a reaction to being looked at.
Rock throwing needs to aim in the direction the camera is looking, rather than the direction the character is facing. Makes it very hard to use quickly or accurately when a distraction is needed.
Whistling already has the tradeoff of attracting enemies to your location, so I don't think it needs a cooldown on top of that
To sum it up, I think you could have any 2 of the below but not all 3. It's OK for it to be difficult, if you're aiming for something hardcore, but the foundation is just not working as-is.
- Very open areas with not much cover
- Escaping is nearly impossible because of stamina limits
- Enemies can see very well
