Well, I got all of the in-game collision sorted out finally. That was an odd bug, but it's fixed now and it works a treat. It's much safer to explore the maps that the algorithm generates now since there is no risk of running off the edge of the map!
Another little feature I'm currently working on is that when you click on an object in the scene that you want to interact with, it pulses white briefly, just so that you can see which object you've selected. It's only a subtle touch, but I'm all about the user interface!
Well, it's 3am, so I'm off to bed.
