And this Angular version doesn't leave graphical debris all over the window in FF on FreeBSD, big win, sort of the reason I turned my awk script that I ran to test strategies for playing the original game well into an interactive game itself ;)
Seriously, screw TodoMVC. I cannot get a feel for a framework from that. This is almost the minimum complication level you need to be able to assess a framework's usage complexity.
The animations need work though, the feel of the game is less polished than the original, mostly because the original game keeps a copy of the most recent tile floating on top of the one that's merged away so that the full animation can run.
