if they decline, some other possible sponsorship ideas...

Big thanks to Eduardo ( @martiano ) for giving a micro-talk on his Try Omarchy project at our rl monthly meetup in Kyoto last night. but also... sharing that he's played Growtopia since he was 11 and some various uh, technical tricks he did with it

Trying to put my (literal) finger on why Wolverine's controls feel so mushy. I think part of it is it can randomly take up to a SECOND to actually run after pushing the run button!

Very early engine test of a new game I'm working on! By the way, did you know the best thing about being indie is being able to put yourself (and actual building) into the game? I mean, they say to make what you know... (unnamed, but will be psychological horror)

Astra's visual understanding is next level. bought four dog lights and THREE already have broken clasps. From images (and a few measurements) it was able to create a working 3d printable replacement

I'm steaming now! Help me test out gamebot, an all local AI that tries to beat infocom games. (it listens to chat for help, I'm sure that won't turn out badly) twitch.tv/rtsoft Planning to leave it on a few days

3ds support (using a modified Azahar) coming to HoloVCS's github soon! (runs on Looking Glass 'holographic' displays) - I've introduced a new "mode 2" especially for this, it's pixel accurate, works much better than the 'diorama' method I used for virtual boy/nes

Progress! (Azahar 3ds emulator running through HoloVCS/Unreal 5.8 on a Looking Glass Go)

Patchy Image Editor (an open source photoshop alternative) V0.90 released. New features: Scan and divide images, Photocopy (via scanner and printer), image to shape/svg tools, deep PDF support, load/save/edit gif animations: github.com/SethRobinson/Patc…

Playing Zelda on a $99 Looking Glass Go 'holographic' display. Big thanks to @LKGGlass for open sourcing their Unreal plugin - got it updated for Unreal 5.8 and hyper optimized for my project. (100x faster quilt rendering!) github.com/SethRobinson/Holo…

Ha, found an ancient Windows build of Growtopia from November 11th, 2012 (Buildo.exe) labeled "V0.01". Can't actually play online with it, I tried :D That slightly disturbing text on the about screen survived until 2018 I think (?)

Been organizing and cleaning... surprised to find FIVE GeForce 1080 cards in the closet. Built an open 'bench machine' with mostly old parts (spent $300 for new MB+CPU) to make testing easy so I can sell 'em on Mercari. ($80-$100 range?) Old, but still a capable GPU.

It has come to my attention that owning nine DDR pads is "freakish" and that I "need help." Well, my retro collecting obsession is your gain! These (and more) will be on the free table at our next meetup. Please, please take them.

Two months ago I started working on Patchy, an MIT licensed cross platform photo editor. In addition to "properly feeling like Photoshop" it is the only open source editor that can handle 25+ years of my .psd files (including re-saving) accurately. Canceling my PS sub
