[1:45:18][@magzz772][Q: When will you be fixing the :lighting?]
[1:45:22][@mycon_][Q: What's your all time favourite game?]
[1:45:30][@wheeel][Q: Is there going to be :lighting affecting the shading of the entities? If so, would that lighting strength be uniform along the height of the entity within a square? Is it possible to make the lighting of a 2D entity in a 3D space look "right"?]
[1:46:09][@mycon_][Q: Is there a bug now that the guy is pointing left constantly?]
[1:46:57][@jim0_o][Q: Thoughts on creating some sort of weather system and / or sun noon, dusk, etc system?]
[1:48:02][@mycon_][Q: It seems the tree graphics are for different seasons. I don't think the evergreen one is supposed to be damaged. Also you already have tags for seasons like Tag_Winter, so the Snow tag is kinda pointless?][:"asset system"]
[1:48:25][@alexkelbo][Q: How will we do shadows? In the past we had a bitmap for that][:lighting]
[1:48:54][Replace the "snow" tag with "winter"][:"asset system"]
