Some progress made. Below you can find the updated game link, link to the current commented .CAPX, and links to sources I cobbled together to make this happen. The last major feature I need to tackle is only rendering what is on screen with like a 10-20 tile buffer off screen so I can really make this a HUGE world without hitting performance issues. My current tiles are not seamless due to my lack of bravado within Photoshop, but hopefully I can make or find better ones in the future, probably find.
