Normally I do itch.io covers for video games using art from the game. For Last Voyage of the Tartarus I think I'm going to use collage instead.

Collage image of a sailing ship in a land filled with icebergs and ancient ruins. The sky is full of images of undersea life. The title says "Last Voyage of the Tartarus".

Screenshot of a tilebased pixel art game. A sailing ship is moving across icy water towards a green stone shore covered in alien buildings. Light pixel snow flakes cover the screen.

Working on a #PROCJAM 2025 entry. Reusing a bunch of my Archipelago of Monsters code to create a polar expedition game. Gonna get weird with it and take a lot of inspiration from The Iron Coral from Into the Odd.

Maybe going to make a Vaults of #Vaarn #PS1 style game?
Video game screenshot with PS1 style graphics. A lady with 3 arms looks out at a blue desert landscape. The landscape is stormy, and there are pink trees rising out of the fog. The trees look like Socotran bottle trees. The lady is wearing a backpack, combat boots, purple pants, and a ragged coat. Her clothes is stained with blue sand. Her hair is purple.

My game is going to have more accurate bronze age armor than Christopher Nolan's Odyssey movie.

Here's another shot.
Another classic UFO image viewed from the side over a desert landscape with sparse bushes. Black and white. Rendered in Unity.

I'm looking back at the UFO game I was working on and thinking maybe I should try returning to it.

#gamedev
Black and white image of a classic 1950s UFO flying in the night sky over a mountain. You can see the rough edge of pine trees on the mountain. The image is rendered in the Unity game engine.

I added a perchance generator to my Vaarn jam submission. Should make it easier to roll.

Now that I'm thinking about it in the DCC Day 2021 Adventure Pack the adventure Temple Siege is essentially a 1 room adventure.

Updated my zine shelf. #rpg #osr
Sad you can't really see what the zines are, but not a lot of options there.

Collage of a crab and steam ship components combined. Numbers and sketchy lines superimposed on top turn the crab ship into a map.
