Yeah, the game really takes a toll on you. Glad knowing you're enjoying it...
Once you're done with the base game, you should try the mods made for the game. You can find some here: DokiMods
Or you can search up mods in Reddit or other places.
I went in blind. The only hint of gameplay I saw was like in VN videos explaining about different and unique VN's, but I skipped DDLC because I wanted to see it for myself. And oh gosh I was broken from that for 2 days.
Then I made it worse with some mods. This game made me depresso expresso for an entire week. Still, cool game, and some mods are really fun to play!
