This is a game I started working on around 3 years ago.
After some months I had abandoned the development of the game, but recently I got back into it, finished it and published it to the Play Store!
It is a colorful and easy going game, where you have to pop some balloons based on colors.
The leaderboard stores and retrieves data using a TinyWebDB database component. Before, it was connected to a custom TinyWebDB service on Google App Engine like it is explained here: Custom TinyWebDB Service
Lately, as Google App Engine is now requiring a credit card to function even in free tier, I moved the custom service to another host and now it uses TinyWebDB-PHP (google it to find it) to manage the data read/write operations.
