Well, to be honest, I don't mind they ripped off my demo. It's not like it was a substantial game. The only two issues are this.
1. They didn't, and refuse to even mention Construct or the original Ghost Shooter demo, even on other websites, true to their censor-their-own-forums approach. Rejecting Construct from the Clickteam-run Gamebuilder site is another good example of this. If they'd just been honest and said "Here's a clone of Ghost Shooter from Scirra that shows MMF can also do this", I guess none of this would have happened.
This is trivial compared to the next point though.
2. In Clickteam's eyes, this demo is OK because the graphics and programming are original. The fact it's the same idea doesn't bother them. It made the front page of their site.
When they were telling me (very explicitly) that they were about to sue me, the only problem they had was with the ideas behind Construct. The whole legal threats thing lasted a long time and they even rang my mum (??? I'm over 18 and can deal with this myself thanks). They obviously feel strongly about the protection of ideas.
Endorsing the 'Ghost Hunter' demo is blatant hypocrisy and if they don't retract it, they are absolutely crazy.
