This is a seriously simple but addictive game.
It’s free but it makes revenue from ads. It’s a simple development from a Vietnamese developer and found success when the app became popular with more than 50 million downloads and raking up more than USD$50k per day in online advertising. Not too bad for an Indy or independent game developer.
Anyway I started playing it and it was extremely frustrating as the game play was pretty challenging at first. So I finally manage to get through more than 10 hoops and won a medal. That was a good feeling. Amazing how games can shift your emotions even just the slightest way.
