Why are people thinking multi player option isn't that necessary. Given the fact that there is over 30,000 single player flash games out there, and that is an understatement. Even if you did make a really good game in html5, chances are flash already have something similar, and a lot of people play it on the computer not the phone. Plus, if people want to play a good games they go to the big 3D games that you purchase, they just want to have fun and try something new. Having multi player options will build spread the game with it being kind of a social connect thing too , not just a game. Also the debugger can be built using text box or something, if you can't built a debugger yourself than Construct 2 is to advance for you or you have a hard time figuring out problems even with a debugger. The debugger won't tell you logical errors or stuff that you cannot realize yourself. I'm not discouraging building a debugger, but I don't think it will help Construct2 that much.
