While Rocket Cat's endless puncher might be gaining critical acclaim, the number of people who are actually spending money on its in-app purchases is almost non-existent.

Speaking to Pocket Gamer, designer Kepa Auwae stated that while over half a million people had downloaded the game, only around 0.01% of them have actually spent any money on it.

"We really needed to get seen by more people, and Punch Quest accomplished that while giving us a ton of success with review scores from major sites and acclaim from iOS gamers."

It's not unusual to see the less vociferous freemium titles suffering. Earlier this year Solipskier's Gasketball suffered a similar fate, with an even more dramatic consequence. Auwae isn't too down hearted though.

"As a paid app, we would have made much more money, but we wouldn't have been nearly as visible or gotten even close to as many downloads."
