The part that perked my eyebrows the most had to be his first introduction, and seemingly only mentioned one, to be what I think was iRogue---the very first "Rogue" port/version the iPhone received and it was very....not looked favorably upon....and as it turned out the Roguelike slate on iPhone proper REALLY got started with RogueTouch a bit later and now there's so many more.
So, even if he was trying to stay in the, er, shadow of something that I don't know is capable of casting one, iRogue, wouldn't logic dictate that other iPhone offerings and perhaps PC offerings would've followed and colored his notions in a wee bit more?
I hope the developer comes to investigate Roguelikes a bit more conclusively as opposed to seemingly thinking he'd struck gold fomr iRogue and all others are just derivatives. I mean, if he'd used Google even a single time I'm pretty sure the top many search results would've exposed a great deal more. 9 months on this versus many 7DRL's but to the latter's credit they've a more logical cohesion and vision going on.
