I love Construct 2, but I've been looking at returning to Linux as my OS for a while now, it would be amazing if Construct 2 would be ported to support it, I know its not something that couldn't happen over night and with such a small dev team I don't see if being done anytime soon.
I found that 'GameDevelop' through a friend who linked me to it, its pretty great actually, as with most open source things as of late. I will likely be using that over C2 once I do make the switch from Windows to Linux. I'm looking into another possibility too though, I suppose if I can get my hands on a cheap laptop (windows based) I can continue to use Construct 2 on that.
In any case, it would be great to see this eventually
I think my solution should work find for now, using a pre-owned laptop that I can hopefully find for cheap to just use for my HTML5 game developing needs after all, I still have my copy of windows 7 here XD - Sorry guys just kinda thinking out loud through my reply :S lol
So, +1 to Linux support from me for whenever it may be possible!!
