Mind the gap
A quick turnaround for this feature, as the last update was yesterday. I wanted to push this feature through as it'd look quite pretty, and would mark the tiles as complete for the meantime. The image above shows the new, snazzy game tiles. No longer simple blocks of green, each tile has 4 blocks. A red block represents no pathway between the tile and it's neighbour in the given direction, and a green block represents that passage is possible. This will be very handy for the pathfinding (next) as the tiles themselves know where the walls / drops are.
While it won't help with movable blockages, it's good enough for getting a basic pathfinding system together.
