Updated modding guide

Did you know you can mod this game? Without having to use any playdate dev tools? Yepp, thats right :)

Most of the graphics are stored in 24-bit bmp file format which means you can mess around with wall textures or even enemy graphics if you like. You can also easily create your own maps using the "Tiled Editor".

I've updated the guide as the game has grown and there is more stuff you can do in it. The modding guide can be found in the "RedTerror_modding_1_9.zip" file.
And if you create something cool - please do share it! I'd love to see what you came up with.
