Since this game is in the more or less early development, I will only accept pull requests which add an immediate benefit. Please understand that low quality PR's might be closed by me with a short comment explaining why.
**If you want to add a new building, please understand that I can not simply add every building to the game!** I recommend to talk to me before implementing anything, to make sure its actually useful. Otherwise there is a high chance of your PR not getting merged.
This project is based on ES5. Some ES2015 features are used but most of them are too slow, especially when polyfilled. For example, `Array.prototype.forEach` is only used within non-critical loops since its slower than a plain for loop.
You will need a <ahref="https://www.codeandweb.com/texturepacker"target="_blank">Texture Packer</a> license in order to regenerate the atlas. If you don't have one but want to contribute assets, let me know and I might compile it for you. I'm currently switching to an open source solution but I can't give an estimate when thats done.
