- •Wiring system with analog signals adds depth beyond simple block placement.
- •Daily update log shows active development and consistent polish.
Weaknesses
- •No multiplayer yet, which limits longevity for a building sandbox.
- •Browser constraints will always limit physics complexity compared to native engines.

Post Description
I’ve been building a browser-based vehicle sandbox over the past few months, and it’s finally playable
I will continue polishing the game daily so there is more to come :D but the core is in place. I would really love to add multiplayer soon.
