i make games and silly code demos. some free gamedev tutorials: http://demoman.net buy "Trackminia" on the Playdate: https://play.date/games/trackminia/ older games: http://2darray.itch.io

a video of a 3D renderer for the playdate handheld console, showing a camera floating over some misty terrain which might be a golf course. this device only supports fully black or fully white pixels, so all greyscale values are achieved through dithering.

another platformer level, where the player has to avoid several electric-looking obstacles
the platformer character runs and jumps around, leaving a long trail behind them as they move through a level
a video of a low-res black-and-white platformer game, with a level themed to look like a halfpipe at a skate park. the player repeatedly drops into the bowl to launch out the other side, gradually getting more speed and reaching higher platforms while unlocking a series of doors. once they unlock the final door and reach an ending zone, they do a few victory hops.
A screenshot that looks like a scientific paper, containing the following text: Chocolate chip cookie allocation formula The following calculation is used to determine the fraction of the chocolate chip cookies which go to me, while the remaining cookies all go to you. Let theta be greater or equal to zero, representing the cookie elasticity, and let omega be less than zero, representing the chocolate chip cookie melting rate. (At this point a strange looking mathematical formula is shown) Parameter selection We set theta to a value of 0, and we set omega to a value of -1, as recommended by leading bakers, such as Tom Marvolo Riddle. You've reached the usage cap for GPT-4. You can continue with the default model now, or try again later. Learn more (At this point, the content of the image ends. When the above parameters are applied to the formula being described, it always resolves to exactly 1)

more footage of the lantern game. the player starts near a swarm of roaches, which are making loud skittering sounds. the player walks into the swarm and starts getting chomped. with each chomp, the screen blacks out momentarily. eventually the player takes too much damage, and the screen cuts to black. the text "you were killed by a swarm of roaches" appears
footage of the lantern game. the player walks near a giant patrolling spider, and when the spider spots the player, it growls and gives chase. the player hides beyond a small doorway, which the spider can't fit through.
more footage of the lantern game. the player moves through a large corridor, stopping in various small nooks and crannies. a giant spider patrols the corridor, chasing the player when they're out in the open. the spider is too large to fit into the smaller hiding places
a video of the lantern game. the player walks down a corridor and turns on their lantern. they reach a small room, and see a large spider crawling through a nearby passageway. the spider disappears into a corner that's too dark to see, but which looks like it might connect to the room that the player is inside. the player waits nervously and starts to back away. thankfully, when the spider finally emerges from the darkness, it's moving away from the player's room.
a screenshot of the lantern game. a dim light illuminates a bendy corridor
a video of the lantern game, which looks about the same as before, but now the camera can pan around to follow the player through various rooms, instead of the scenery always being locked in place on-screen.
a video of some console-output, showing the results of the script from the previous post. the output reads: Steve: You're new. Are you here to help? Choice 1: Yes. Choice 2: No. > chose option 1 Steve: Awesome - we need to find a lantern. [end of script, press button to talk again] Steve: No lantern yet? Choice 1: Not yet. Choice 2: Yeah here it is, it's too bright to see it. > chose option 2 Steve: Cooooool, sarcasm. Very cool. Very mature. Choice 1: Yeah I'm the most mature toddler in school. Choice 2: Sorry. > chose option 1 Steve: Just...find a lantern, dude. [end of script, press button to talk again]
some code in a strange format which has logical flow like if/else, but also lines of theater-dialogue like "name, colon, spoken text" mixed together. there are a few spots where the player can pick something to say, and they get different responses from the character they're talking to depending on what they picked.

a low-resolution waving flag, animated in pico8. the flag says the word "SHIT" on it
footage of the lantern game. the player moves through some rooms and a swarm of small bugs follows them around. eventually, the player turns on their lantern - the bugs stop trying to get closer when they reach the edge of the lantern's light. the player moves around with their light enabled and can sort of push the bugs away.

footage of the lantern game. the player stands still, illuminating a pitch-black room with their lantern. a giant centipede-like creature emerges from the darkness, circles the player, and then exits the room.
footage of the lantern game. the player holds a light in an otherwise pitch-black area. a giant spider emerges from the darkness and chases the player down - the clip ends right as the spider reaches the player
more footage of the lantern game. there's an ambient light-level across the scene, so walls and floors are visible even when the lantern isn't directly illuminating them. in these ambiently-lit areas, spots on the floor which are close to walls are a bit darker than the spots on the floor which are out in the middle of an open area. in general, this gives a bit soft shading to the scene
a recording of a grid-based map editor. the user draws some black wall-tiles into the map. any time any changes are made to the walls, some red rectangles inside the map automatically update as well. the set of red rectangles always covers all available floor space, and the red rectangles never overlap each other.
a screenshot of the lantern game, showing the rendering features described by the main text of the post
another clip of the lantern game, this time focusing on an example of the shadow behavior as described in the main text of the post.
a top-down view of a black dot moving around a scene. the dot emits a large circle of light, which gets blocked by various black walls. shadows cast by walls have soft edges, and the softness varies based on the conditions of the shadow.

a video showing the process of pasting a tweetjam's code into the online pico8-edu editor, and then running the program. when it runs, it draws the red planet from the thread's original tweet
a noisy low-resolution rendering of a slowly-rotating red planet with some wavy patterns stretching across its surface
a replay of a race with cinematic camera angles, now with audio synced up to the footage
Another clip of the racing game, this time with a regular gameplay-style camera which stays behind the car. The video is using 1-bit colors, so each pixel is either fully black or fully white, and lots of dithering is used to give the impression of in-between grey values.
A video of a low-resolution greyscale racing game. The footage shows a replay being viewed instead of live gameplay, so it uses various cinematic camera angles instead of a view from behind the car.
