Cons1 is no more. 2 years of waiting with the sad conclusion.
Cons2 goes with HTML5 support that works terribly slow (based on the HTML5 demos). Stencyl is very slow too.
The fact there's no unhappy person about it really creeps me out x_x. Cons1 will remain buggy, it's a disaster. Ashley I hope you provide us with great development tool this time. Please make good development decisions and don't get too much of suggestion from this always-enthusiastic audience. Good luck!
