Been adding some more features to tilemaps. Setting tiles to be collide-able on specific sides should now work (getTile(1).collision = LEFT | UP for example). Also, you can now set tiles to be one-way. For example, the cloud tiles in super mario world you can fly up from underneath and they aren't solid, but if you land on top they are. In that case, you'd set the tile's collision to UP and oneWay to true.
I have only done limited testing, so if anyone has a game where they could test out whether it breaks anything (either the new features or old) that'd be awesome.
