    • Neat viewer. I wonder, why boats and cars in groud view ended up in such high altitude?

Objections

  • Web viewer freezes on mobile phones and is heavy.

    • this is not jpg or png but some dynamic stuff. It freezes up my phone. Why do you need to complicate the stuff so much? Direct jpg or png could be rendered even by pentium 100…

  • Maps only shown as 3D rendering, no static images on page.

    • Not even one map as jpg or png to see on the webpage!!! Whats the point of this project? You expect us to load npm just to see some maps?!

Requests

    • Sorry, the maps are rendered in 3D so that you can fly around. I can of course make top-down screenshots of the maps. Thanks for your feedback.

    • Stunts was the greatest! You could make your own tracks, save replays and (IIRC) even resume gameplay from any point in the replay. My very favorite game of all time.
