I’m sure it’s the most profitable way to do an app like this. Make the game short, easy to learn hard to master, and give it a huge positive feedback loop. It’s the reason why I paid to remove ads in Pixel Car Racer.
But this game is so eager to feature the most generic and annoying in-game ads that it ruins the solid base this game has.
Every once in a while I’ll install a game to see if mobile gaming has gotten better, and every single time I’m reminded that mobile gaming is still the most consumer-unfriendly platform there is.
