It is funny seeing some folks get all pissy about HiTech devoting time into this mini-game. News flash to you guys, in case you were not aware, coding something quite large takes A LOT OF WORK, more so since HTC's team is small. I think one reason it was done was to take a little break from the main project. It is also possible that they are testing something out, to have a rough idea if it would be worth working into the next update or not.
I rather they take a break doing something else, which in this instance turns out to be something we get to mess around with, than to burn out and give us a sub-par release.
