There are a bunch of submissions and I wanted to give feedback to everyone, so I'm going to list some strengths and weaknesses that I perceive from the GDD's in this challenge (take with a grain of salt, I recognize the challenge this jam theme + time limitations, especially during a holiday weekend).
Strengths: The game seems very cute and fun. I really appreciate you using diagrams and GIFs to clarify things in the document. I completely understand how the game is meant to work in terms of game loop and "enemy" behaviours. I would actually consider the idea of the "Super Spookyhouse Maker" as a real win for this game. If you can use this to allow your player base to mod the game and add their own designed houses, the game could have an amazing community and add extra content to your game for free!
Weaknesses: I don't know how different this game is from other POP (as you call them, and so will I forevermore) games. I think it fits exceptionally well, but I think adding rogue-lite is a little misleading. The game has some replayability in the procedurally generated houses, but it requires more mechanics to classify as having rogue-lite elements. That said, I think it would be fairly easy to remedy this.
Overall seems like a fun game, but some additions to this game would make it a knock out for me.
