I’ve signed up for the game jam, but I don’t currently have 200GB of disk space available to compile the engine for WebAssembly projects. Could you please upload a preliminary version that includes WebAssembly support, so that compiling the engine isn’t necessary? I’m really glad to see a modern version of Unreal with HTML support; I’ve consistently used HTML with Unreal for most of my projects on [itch.io](http://itch.io)—specifically versions 4.23 and 4.27 (the SpeculativeCoder version). An important aspect of the browser is its support for mobile touch; a well-optimized build for mobile should work very smoothly on any reasonably modern smartphone. I encountered quite a few issues when trying to emulate touch input in older versions of Unreal. Joystick support is also somewhat poor. I was unable to get the API implementation—for example, for Facebook Game Room—to work. I’m glad to see HTML making a comeback in Unreal! > **[GitHub - SpeculativeCoder/UnrealEngine-HTML5-ES3: Unreal Engine 4.27 HTML5 ES3 (WebGL 2) & 4.24...](https://github.com/SpeculativeCoder/UnrealEngine-HTML5-ES3)** > > Unreal Engine 4.27 HTML5 ES3 (WebGL 2) & 4.24 HTML5 ES2 (WebGL 1) > **[Brick Car 🏎️ #UnrealEngine by Ariel Gimenez](https://kone9.itch.io/brick-car-game-unreal-engine)** > > recreation of the brick car game with unreal engine and blender3D ---

Okay, now the question everyone wants answered about your new vibe-coded version of UE: does it start 4.6 seconds faster than Steam? Let’s go sweeney, you can do it! ---

Soooo, to be clear, does the 5.9 preview release currently available on the launcher support shipping with WASM out of the box, or do you need to download the source version over at github to be able to use WebAssembly/HTML5 as a target? ---

I was about to say “don’t listen to the haters,” but… I can’t even find UE 5.9 for the Jam in the new vibecoded Launcher. So I guess the haters kinda have a point, and maybe you should listen to them. ---

why even let real ppl join the game jam, just have agents do it themselves at this point lmao. I’ve used Unreal since the first UDK version and its decline is very sad to see, please just keep the slop for 6 and make an actual LTS version for 5, that’s all we ask. 5.8 is great but i am not motivated to upgrade to 5.9 except for the wasm support ---
