Congratulations to the entire team from Shirakumo Games! Developing and shipping a full-fledged video game requires a lot of hard work and dedication. And writing a custom game engine and tool chain at the same time is really a heroic feat. Hats off to everyone, especially to Shinmera!

Congrats to the Sandra team, sorry about the off topic.
I was originally a Kickstarter backer when the developer was advertising the game as intended to be open-sourced, but then open-source became a Kickstarter goal so I withdrew the backing.
The source code for the engine, Trial, and the game, Kandria, are both open and on our GitHub under Shirakumo.
Earlier quoted context omitted.
I had to do a little bit to avoid insane amounts of consing, but honestly not a lot. And the optimisations I just did after the fact, gradually. I use CLOS a lot for everything. The event system is literally just an array of handlers and a generic function called HANDLE that takes the event object and the handler object, for instance. The source code for the engine, Trial, and the game, Kandria, are both on our GitHu…
Nice! Thanks for sharing! Update Bought a copy, definitely my jam. Played on the steam deck, noticed that the first time I used an action (move, jump, attack) there was a noticeable pause/stutter but has been smooth as butter afterwards. PS: are you able to talk about the steam integration? I assume it's a C or C++ library of sorts and fairly straight-forward to extend; curious if you plan on releasing to another pla…
Sure. I use the cl-steamworks library I wrote. https://shinmera.github.io/cl-steamworks/ Their API frankly sucks and getting the integration going was a big pain. However, if all you want is the minimum, like achievos, you can omit all of that and just do a couple C calls.
The engine has abstracted support for achievements and such integrations, so it is possible to integrate with other platforms, too, should we ever release on GOG or EGS.
Hey, why does it matter if it's made in 'common lisp' ?

Ah that explains it! Congrats on shipping on Steam!
