    Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users.

    Just launched a very early beta of a multiplayer "FPS" made in WebGL using ThreeJS library. (possible to switch between FPS and 3rd person) Just a hobby project that I would love to get some feedback on, in order to see if I should continue working on it or not. Note; It will add the project to github as open source once I've spent some time cleaning up the code. URL: http://wizardwarz.nergal.se

    Made this to try out o1-preview, took ~40 prompts and 3 hours in total, with a fairly solid backed written in Go. Works pretty badly in Firefox apparently due to canvas-canvas copies being really slow, Chrome works great tho. Doesn't work well on mobile yet, and has some other minor issues, but overall it feels incredible to put together something like this so quickly.
