I feel that everytime I use C2 to make a game, it get´s closer to my dream tool, but then I hit a big stone wall and have to rethink all my game. After multiplayer I really hope the focus to be on monetization(some of us want to make a living) and feature completion. More system expressions, more control over the insides of the product and much less use of 3rd party wrappers, that have been quite unreliable in those past 2 years.
Also, I´ve seen many times the "We´re a 2 man team" answer, but after 2 years and 1 bajillion downloads, isn´t it time to get more investiment/people on the team? You can´t be a serious contender for Unity/Game Maker with two guys for too long. o_o
