Vexed Hedgehogs has 1500 plays at GameJolt. For me, this makes it far more successful than anything else I have made. A couple of my games have clocked over 1000 plays before, but this shows what you can achieve when you replace originality with cloning. Oh.
Mind you, chatting to a proper game developer the other day as he got his 1,000,000 th player for his commercial title keeps things in perspective.
The other joy is reading reviews in Russian, Italian and Czech where the fact that it relies on linguistic jokes that don't translate easily (sorry) means that it has been received as a fairly serious clone of Angry Birds. Oh dear.
