ah! sorry to hear that. i believe it's a WebGL issue of not being able to render textures of certain sizes. i'm going to look and see if there's a workaround to not use WebGL and fallback to canvas only. in the meantime, could you check to make sure chrome is up to date?
Hey! I know why this happens. check this: https://www.browserleaks.com/webgl (search for "vertex shader" ), and I surely that your browser has this warning: "texImage2D: width or height out of range".
It's simple: in your browser WEBGL has a max value to generate texture and this game is above that.
Sorry if i didn't say clearly ( i'm not native speaker english)
