This game is really good and the art just adds to the degeneracy of it all but have not been able to progress without using the universal renpy mod.
1st block in progression was the peeping, the normal event just doesn't fire for me no matter what I do, I restarted multiple times and even tried starting with 2.3 like someone else suggested, I also tried an old fix by the dev with the console command but that just ended up crashing the game after 1 training session.
For those in the same situation what I did to progress was use the universal renpy mod, access its functions (alt+m) and turn can_peep into True but this makes you miss a few events unfortunately
2nd block in progression was finding a way to hide the queens horns, once again I could only progress with the universal renpy mod. I thought the issue could be because you can't access the shop in the first version of the game but even starting with patch 2.3 it still wouldn't fire. My solution was jumping to the event where you hide her horns but this bypasses idk how many events.
For those that can't find a solution and want to do what I did to progress, access the renpy mod and search for horn under the label/scenes options and press jump. It will take you to that scene and unlock it.
You can still understand the game even skipping the blocks like I did but it does suck, I advise unlocking gallery and viewing any gallery events you missed but haven't found a way to view the non gallery events that were missed.
