I love how I've architectured the code in Cosmo Cargo. The core of the game can be played in the code without launching the game in Unity. So we have a lot of unit tests! And with few minutes of work I just added a simulator on enemies inspector that will run a sample fight and record combat data.

Et on répond un maximum aux questions donc n'hésitez pas. C'est un projet, des choses peuvent encore être modifiées ! Et pendant le live, il y en a eu plein, des questions ! 😅
Questions du chat pendant la présentation. Une vingtaine de post-its sur lesquelles ont été notées les questions?

Better late than never: we now have a real task list for Cosmo Cargo 😂 Before we were just adding TODO lists to meeting notes, a true nightmare for any producer.

New prototype means new shitty code! But as an expert, I'm now throwing a ThisCodeIsShitException when it's really messed up, so at least the program knows. #gamedev #indiedev

Late to the party: I'm playing Black Mesa (2€$ on Steam!) store.steampowered.com/app/362890/B... A masterpiece and a labor of love 😍 Half-Life was an incredible experience to me when I was 10. Now I feel like I'm 10 again! The new Xen chapters are absolutely incredible.

Dear scammers, Here are few pro tips thread to successfully steal me a Steam key, so you can feed the gray market/play for free/whatever. 1/ have a working website. Seriously! 2/ have a proper domaine name. Nobody's taking you seriously with a free weird domaine name #gamedev #indiedev
A scammer website that is not even working

Doing "boss fights" without combats/health system is a challenging design task in CTHULOOT. So we experiment with mecanics to annoys players while they need to solve a puzzle 😅 #gamedev #indiedev
