Hi, there. I tried the game out again since the last updates, so I figured I'd comment on the building collision stuff. In short, it doesn't alleviate much of the issues. I know I said "at the least", but it seems I misunderstood how much they block you before even being destroyed. The character still gets blocked at very large sizes and frequently walks in place, unable to reach the very building that's in the way. I'd say there needs to be some size threshold that prevents building collision entirely, but I don't know how much work you want to put into this kind of request on top of everything else you're doing. Might be easier to make no collision a cheat option, if you're planning those.
(Uh oh, l made the thread look weird and disorganized)
