I wanted to notify you guys though of some security flaws within the game.

Probably the biggest issue I see is the lack of server side checks against changes coming from the client. I only tested this out on the player object as a PoC, but it only takes changing a variable within the player object to modify things like player speed, mountable craft speed, etc.

For instance, while you obfuscated the name of the player object within the ig.game object, it was easily found by checking for modifications to the health variable, where another function listed it as ig.game.O1376. This name for this player object is also static for every game instance, so it's easily referred to every time.

Once the player object was found, it's easy to modify the variables and the world (server side) accepts it. It was also easy, for the most part, to identify what certain variables did as they were in plain text. To change player jump height for example, all it would take is this piece of JavaScript:

window.ig.game.O1376.altJumpReducedGravityFactor = 0.1;

Now the player can super jump and the server is fine with it (verified by numerous 'holy sh!' and 'wtf!?' comments from other players).

The second thing I see is just obfuscating the code more.

I would suggest first and foremost to do the server side checks. Even if you left all your code in plain text, any modification someone tried to make from the client would be seen, verified, and handled accordingly by the server. Second I would try obfuscating all variable names that you can, especially the class definitions like EntityPlayer. To go further on it, I would have it produce the obfuscated names randomly on each load of the game script so they're not easily referred to.

Just wanted to bring the issue up to you guys after finding it.
