UPDATE: 20280826 – Made a Microcontroller joystick controller for the maze game.

Realtime draw maze using php gd lib

Above test was abandoned, it was working okay.
But I made a V2 using some vibe coding … yeah, I know …
Time to shelf …

Works:

• Mqtt websocket
• Multiuser
• Keyboard control
• Fire/kill detection
• Admin view

No working / needs work / nice to have:

• Restart after kill, resets score
• Set own username
• Sound effects?
• Degrees are > 360 .. lol
