Are more "troll" than bad endings, but you're right, a bad choice can lead you to a game over, as a tip, you can save when a choice appears so you won't have to start the game from the beginning; the only "hard" part I consider, maybe is "the halloween special" (v0.3) or on the first night; the game isn't long, but this don't mind that is short on content; but don't worry if get stuck on any part you can ask me for an advice.

Really the game hasn't an ending now as is a early access, if you want a guide you need to ask me on Patreon, as this site don't allow private messages, also my other game "My New Daughter's Lover", don't have choices that lead to a game end, you can try that game too.
