😓 NOTE: ごめんなさい (Gomennasai)

🚮 HTML5 Browser Version runs worse (Mouse is glitchy; etc.) than the

🗑️ Electron Browser Variants; and these all run still way worse than the

native 🐧 Linux or 🪟 Windows versions.

... and... yeah... the "NEAT neural network" is still pretty dumb too xD

Install instructions

🛠️ Fix for AppImage not launching on Linux (FUSE error) 🔧

1️⃣

Open a terminal directly in the current folder (pwd)

e.g. KDE Plasma / Dolphin:

Right‑click → “Open Terminal Here”

...or press Ctrl + Alt + T, then "cd /path/to/Hw_Electron_DEMO.appimage"

2️⃣

Extract the AppImage (=Required Fix)

This bypasses the missing FUSE library and unpacks the game.

./Hw_Electron_DEMO.appImage --appimage-extract

3️⃣ + 😙 + 💖

Run the extracted game

The extracted version does not require FUSE and runs normally.




🛠️ For the native Linux Version, check "Troubleshooting.txt" 🔧

Use the "run.sh" (make it executable before doing so!)
