Why? Can you explain? The only missing parts doesnt look like tricky to code to me… I feel like they dont want to reproduce the system, not that they cant. I heard that traditional stopwatch system is too hard to understand for newcomers, but hey, all the sytems you proposed so far are even more complicated. Everytime you discover a game you have to adapt and it takes time to fully understand it, doesnt mean you cant enjoy it …
One more time, sorry if im not clear enough
