@Kylaila: I just came up with the idea; I know how the story will start and end. I know what I want to do with the dungeon and I really like the setting of being inside some rich guy's enormous basement, looking for a killer clown! Overall, it seems very simple and it's probably something that I'm able to do. I've looking for ideas for shorter projects for a while, and this one simply rings a bell for me.
@mawk: You really don't want to know. Trust me.
I've been wanting to make a game like this for years too. I also made a similar dungeon for an old project. Making this small game feels like I'm making a spiritual successor to my old and lost projects. It already feels like a labor of love somehow. x'D
