Honey In The Rafters is an adventure for Mausritter---a 24 page clever boil-down of That One d20 Game That Everyone Knows.
HitR, like Mausritter, has extremely strong art and layout. It also packs in a lot of content in for a three page adventure, with new monsters, new spells, new items, a table of curses, etc. The dungeon itself is a one-page affair, with rules text overlaid on the art, and it looks great. An advantage of Mausritter is that you can basically take any normal human-sized structure and it becomes a cyclopean megaruin for mice, and HitR uses this to great effect.
If you like sword and sorcery ttrpgs, and OSR, and extremely good layout, and probably also mice, I'd strongly recommend following the link from the page text and checking out Mausritter if you haven't already. And if you already have Mausritter and you're looking for a one-shot or a convention game or just a simple but flavorful scenario to run in between your own content, Honey In The Rafters is absolutely worth picking up.
