Making good progress on my #7drl project. Captain Yendor's Lost Treasure. Here's a title screen test.

Me too πŸ˜‚
I still have no idea what it's going to feel like since everything up to this point has been building scaffolding and data structures for the rest of the week.

Lots of text on screen. A roguelike screenshot. Describes a ghostly pirate crew with various abilities, a ghostly pirate ship with different stats, and a ghost pirate captain.

Today I've got almost all the ship, crew, and captain generation finished. No ship names in there yet, and there are a bunch of other details. But almost there.

Ascii roguelike screenshot. Shows a map screen overlaid on the main game view. The map is mostly brown and very abstract. A title says Treasure Maps, and a subtitle says The Known World.

Working on multiple screen layers for popups, and a treasure maps popup for my #7drl. The overall world map here is a little odd, but I think it'll work. The idea for treasure maps is that you'll have to sail until you find an island that matches one of your maps and then travel to where the X is.

More #7drl map generation progress. Different colors show sand and vegetation. There are atolls, mountains, rivers, lava, ruins, palm trees, and coral.

Progress on map generation. There are different sorts of island chains. Each color will be either a different civilization or a different type of island.

Working on map generation. I'm going to use noisy voronoi cells for islands. Clusters will be combined in various different ways to form an archipelago. Some islands will be large clusters, others thin strips.

Going to make this a thread for my #7drl progress. Game is pirate themed. Going to be all ascii and moderately traditional, but taking a lot of inspiration from FTL and Sid Meier's Pirates. Going to go weird and fantasy with it though, with ghost, monkey, shark, and crab crews.

Started working on my pirate themed #7drl project. First thing I'm doing is pulling colors from various Treasure Island frames to make a palette.

Clerical Errors Tony DiTerlizzi β€œFixing the cleric” is about as common in OSR circles as β€œfixing the thief”. The cleric is also frequently cut from campaign...

My campaign to replace the D&D cleric with the Earthsea-style wizard and the Tolkien-esque elf continues apace

Hey thanks for playing! This one was a ton of fun to work on. I think I'm going to participate in the jam again this year.

I'm getting hyped for the #7drl in a few days! I think I'm going to try to make a pirate themed game. Something about finding captain Yendor's buried treasure.

Scattered Wings by Jacob Marks An interactive Lynchian nightmare

I mostly finished my submission to the Catch ideas LIKE FISH. David Lynch Game jam. Pretty happy with it, even though I couldn't finish it. I just lost motivation and wasn't feeling like it by the end.

Yeah don't do it if it's anxiety inducing πŸ˜…

There's a nice dungeon crawler discord community associated with the jam though.

Looks nice! You could check out the Dungeon Crawler jam and use what you have as a base. itch.io/jam/dcjam2026

An art teacher I had suggested collecting sports magazines for dynamic poses. I never would have thought of that, but it's certainly better than google.

So cool. Can you do anything with the cork, or is it just a decoration?

21.02.2026 06:03 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Of course in my experience combat isn't like that because players have abilities, I don't play npcs as unerringly bloodthirsty, and players come up with smart tactics or flee.
