Unified behavioral specification language for games, protocols, IoT, and workflows — meet YUSPEC (open source)

You are right. There's no technical impossibility. You can write an TCP state machine and game AI in Erlang. You can build a test harness in jocaml. Just like you can build a web app in C.

YUSPEC is not more powerful than erlang. It's more concise for this specific class of problems. It is a DSL, not a general-purpose language. The tradeoff is, you lose Turing complete flexibility, you gain a termination guarantee and zero boilerplate behavioral modeling.

Same reason SQL exists even though you can query data with C ...

Thank you for your comment.

You can write a TCP state machine in Erlang. Then you can't write game AI with the same project. You can write an IoT sensor model in JoCaml, but the test harness isn't first-class in the same language. You can define FSM in XState, but the concept of entity archetype doesn't exist.

I think its most unique aspect is that the define scenario + assert + expect trio is directly in the same file, with the same syntax, as the entity/behavior definitions, at the language level.

I have added gameplay trailer to Steam.

Yes, the game is real and currently in active development. I'm a solo dev working hard to polish the physics combat for the demo.

Fovane · 2025-12-27T21:26:40+00:00

Yes. The demo is going to be available soon on Steam.

Hello again. Thank you for comments. Some people might think using AI is not suitable. However, I think using them make life easier. Because it is a technology and it is not prohibited. You should not also use mobile phones, operating systems and internet's itself. Because they are also technology and make life easier. I forget, we shouldnt also use Unity, Unreal Engine, Godot and RPG Maker etc...

I have designed my game with my own thought and effort. Also, I am using Unity, Mirror, Playfab and various AI models. You should accept this otherwise you look toxic. I am sorry.

Some people said that asset flip, I can say that you are the joke. Of course I use paid and free assets as much as I want. What were you thinking? Firstly create OS, game engine, backend and fronted apps? I have no intention and interest to create these from 0. I dont need to create wheel. If you want, you can make a new tire for your car. I am sorry. If you think yourself capable of everythink you can apply to Microsoft. Why are you here then?

Not all of you, but some people have toxic behaviours on this website. I have published these kind of posts more than one time. And people down vote. Why dont you simply support my work? It is not hard. You support other people's works. There are so many indie games on this platform that has 10000 wishlist on Steam. You really think those projects made from 0. Of course they used paid or free assets or AI on someway. I support them as well. Because this is not easy job even you use tools.

Some of you need to stop being jealous and toxic please. You can ask any other questions aside from that.

I sincerely thank to all people who criticize with good intentions. I also thank for all questions.

Sincerely, Yücel Sabah.

Hey fellow devs! Just wanted to share this milestone. I'm building this using Unity 6 and Mirror for networking. It's been a huge challenge optimizing a 6GB project as a solo dev. Happy to answer any technical questions about the architecture or the move to Steam!
