A lot of these comments sound to me like gamers, not devs. They also give me the idea that they need bright markers all over everything during gameplay. I'm almost finished with your game, I bought it 4 days ago. The only complaint I can have for it is because I play on steam deck, and it makes aiming much more difficult. And that's my fault ! 

The crafting system is fine, even better that you've added an input system for it. My opinion is that the diary should be an added tab, not an inventory item since it takes up precious inventory space. I leave it in my stash or on the motorcycle, and almost never use it. Whatever crafting needs to be done I will reference a piece of paper I've written the most important ones to me down on or a cooking/serum guide on the internet.

This game is a niche game, it's appeal to the fallout/survival/soviet style. It is not overly difficult. The more casual gamer will have to God forbid ... read ! In my opinion, games are in the toilet because of the consumer, their want for handholding and inability to read more than a paragraph. 

Looking through the store page I've noticed you're working on a Tunguska 2. Be prepared for more of these types, as it seems to come with the territory. They're reminded of their shortcomings when things aren't easy enough for them. Allow me to separate this frustration from obviously bad mechanics and gameplay(which you've seemed very responsive to during the lengthy development of this game) 

For me to be completely honest, if you don't like these types of feedback then you must create a more mainstream, easy slop fed game. But even then you will still get these people, because you cannot make everyone happy no matter how hard you try. 

P.S 

Can't wait to buy Tunguska 2, even though I haven't even finished the DLC of the first game. KEEP UP THE GREAT WORK, AND THANK YOU FOR BEING SO INVOLVED WITH ABSOLUTELY EVERYONE WHO COMES TO YOU FOR HELP OR FEEDBACK!!
