Hi, colleagues!
I made one more simple game for Android. It's called Kakao (kakao is cocoa drink in Russian transcription).
The game has no original gameplay - you just need to drop sugar cubes to the other cubes with the same color.
Kakao has infinite amount of levels, ascending cubes' movement speed and ... relaxing jazz music :)
I made this game in 20 days. This time was spent on:
making sound effects (2 days);
graphics (I didn't make cubes idle animation);
coding (base code was made in a few days, and the other time was spent on fixing bugs and balancing gameplay);
fighting with haxe bugs (read about them later);
preparing for releasing on Google Play (creation achievements, making icon graphics and promo graphics)
