Clever? Or committing programming crimes?

I’ve been having a blast working on this chaotic little game. Excited to be able to share it!

Doubtful. Sounds like time for some lessons about the coefficient of restitution.

This is Nova. She’s a sophisticated lady.

Close up of a black and white cat face. She has wide green eyes and a black mustache mark on her left upper lip. Her tongue is sticking out a bit and is looking up derpily as if there was something interesting behind the camera person.

I’d absolutely put the big one in. And maybe two or three more. Extra garlic is never a mistake.

Having a blast logging back into this world! This sequel builds on the wonderful strategic roguelike gameplay from 868-HACK, adding a ton of new depth to explore. Highly recommended!

Like, after sunset it sneaks around the back of the earth into the batcave, puts on the snazzy S outfit, and sneaks back into the sky.

Gotta be honest, not being seen at the same time kind of points to it being one of the stars. Like Superman and Bruce Wayne.

Congrats to you and the rest of the team! I played through this over the last few days and found it hard to stop. It’s cute, delightful, polished, and has a wonderfully positive view on human community that feels so good to see these days. Thank you for putting so much love into creating Mythmatch!

Not wrong. I kind of wish it were boxes and triangles. Both kiki, but with the number of sides corresponding to odd/even. And I suppose the word Odd starting with a circle is a reasonable argument for the current standard.

Devin Kelly-Sneed @devinks.bsky.social · 06/01/2026

I’m so sorry, Kee. A lot of what they do with Raz is my fault. I made those bugs.

Devin Kelly-Sneed @devinks.bsky.social · 01/01/2026

Neat concept! Got this in only two guesses because it uses a ruleset I was already familiar with. I like how it highlights the rule violations on incorrect guesses. Looking forward to more!

I just built 5.7 in vs 2026 this past week using the 2022 toolchain. The things I needed in the installer were under Individual Components. Searched for “14.44 build tools”. I think the two things I needed were MSVC and ATL.

Devin Kelly-Sneed @devinks.bsky.social · 13/11/2025

Edit and Continue worked in the gameplay code on that project. Was a delight!

Bee Magic is a wonderful puzzle game (go play it!). Using movement patterns to cast spells creates interesting challenges with the level design. Really nice to read about design iteration on the map!

Last year I wrote about the movement systems for Raz that we built on top of Unreal’s CharacterMovementComponent. This covers the architecture of our Move Mode system, how a few of our custom modes work, and a bit about dealing with inconsistent gravity. doublefine.com/news/behind-...

The most egregious scrabble play I’ve seen allowed is “MRT”. As in the actor Mr T. The folks at that table had a very unique interpretation of the rules.

Devin Kelly-Sneed @devinks.bsky.social · 02/12/2024

I hope to find time to write more of these. It’s great to be able to share behind the scenes info for others to learn from. And the process of writing helps me think about how I might improve similar systems in the future.

I wrote a small series of articles earlier this year about some gameplay features I worked on in Psychonauts 2. A little look into how we built and tuned the systems. Here’s the one about Raz’s jump: doublefine.com/news/devin-a...

Wow, 512 followers! Intro post time! I make games (current: Double Fine, past: LucasArts, Dynamighty). Mostly a programmer, but some design too. Other interests include music (piano and composition), puzzles, and being outside. Quiet, but sometimes I like to write about gameplay systems.

I played 868-HACK during my daily commute for years. Fantastic roguelike with interesting risk/reward choices, simple controls, and turn-based gameplay so you can play at your own pace. Very excited that a sequel is in the works!

I have fond memories of playing a bunch of these with you! Also Mario Kart on the broken tv where green and red shells were slightly different shades of brown.

I have a vague recollection that there were reasons we didn’t use EQS for this feature, but I wasn’t involved in the decision and unfortunately don’t know what they were. Best guesses: EQS being labeled “experimental” or concerns about it being too tightly tied to AI systems.

Devin Kelly-Sneed @devinks.bsky.social · 12/06/2024

Most of the time game thread wasn’t the limiting factor in frame rate. We considered various optimizations (multithreading, storing targets in an octree, etc.) but didn’t end up needing to.

110

Devin Kelly-Sneed @devinks.bsky.social · 12/06/2024

The targets were put into a few different lists based on broad search categories. We’d run through the entire list for the appropriate category. To mitigate the perf cost we tried to order the conditionals to discard as many targets as possible without doing very costly evaluations.

100

Devin Kelly-Sneed @devinks.bsky.social · 12/06/2024

Registration was generally through InitializeComponent/UninitializeComponent. I think those got called when something streamed in/out, but can’t remember for sure. There was also a way for targets to be set Active/Inactive at runtime which let us temporarily ignore them during searches.

010

Devin Kelly-Sneed @devinks.bsky.social · 24/05/2024

I wrote another Behind the Code article about Psychonauts 2! This time I explain how we used our Target Search system. It finds and prioritizes objects in the world for Raz’s powers to interact with. www.doublefine.com/news/devin-t...

Here’s a quick rundown of how Target Search was used to enable that sequence: Player fires Psi Blast. Target Search finds the flying Regret enemy to aim…
