There are great mobile games out there, but I have no idea to find them except by accident.
It's so bad that something like 0.01% of mobile apps make back their investment costs[1]. This is, amazingly, far worse than the rate for indie games on desktop and consoles.
See: 80 days, Sorcery! (really, anything by Inkle), Universal Paperclips, VVVVVV (better on desktop though), and certain visual novels
