I'm really kinda sick of people coming into threads and explaining to the entire gathered masses in that community why they aren't gonna play the game any more. For one thing, literally nobody asked... your opinion on the game is irrelevant if you think that the core of the game is bad, let me spell it out for you: your opinion doesn't matter. You're allowed to have it, of course, but it is completely inconsequential to the thread at large.
If you have constructive feedback or criticism, that's fine, suggest ways in which the game or author in general can improve. Hell I've got a few of them for this game (and others). But coming into a thread and effectively posting "gaem bad lel" only makes people think you're an idiot and bumps up your react score with facepalms.
Do you want to know what the etiquette is for dropping a game? Press the button labelled "unwatch" or even "ignore" if you don't want to see the game again and then move on with your day, it's that easy.
