I'd seen the game before but had passed on it. I liked the developer's attitude and openness and so I just bought it.
"There are days where I just want to pull the plug on the whole thing because I'm sick of 12 year olds (or people with comparable communication skills) trying to convince me they've been wronged and I should give them their 3 dollars back.
...I shouldn't throw the baby out with the bath water. It is a loud, obnoxious baby though."
Which is, btw, one of the best characterizations of the Android ecosystem that I have read in a while.
I hope it will be taught some manners in the coming years.
What we really need to know is (profit)/(development time). And you'd have to match this on Android (or maybe surpass it given his frustration). Even if this took a reasonable time to port, it might be possible that had he worked on his next iOS game, he would have made even more money for his time.
It says how long it took, right there in the article. He says that he had to fight some trouble down the road, but 'porting' was done after a day, due to Unity magic.
Don't forget the extra support time he had on Android. I don't know about you, but I want a high hourly pay to do that.
