Construct is one of those pieces of software that I follow and even put a bit of money into because I like what the developers are doing, not because I actually use it all that much (the other notable example probably being Blender -- I must be the Blender community's longest-standing, least knowledgeable lurker).
A while ago ago I saw an indie dev (can't remember who) prototyping the tiniest little games in Construct, shortly before C2. Nothing special, nothing big, but there was a lot of output. I thought that would be a good way to practise. Lots of tiny little games.
My intentions were good, but I haven't really found the time for a while now. When C2 came along, I eventually got licence, just in case I ever did find the time and because I thought it was a cool endeavour. Lately things have opened for me at work, so... here I am, trying to learn and engage :)
Super psyched for R100 on a number of levels.
