Exported game doesn't work

I export the game (zip) but it doesn’t work on my localhost. I get the a black screen and the following errors.

Odd :thinking: Would you be able to DM me and add yaustar to your project to take a look doing a build myself please? I take a quick when I get back to my desk.

Found the issue, turns out the game code was accidentally overriding the default Map class in JS (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) which the engine uses.

This created exceptions in the engine and stopped the game loading correctly.
