I want to do this puzzle for a while. It's based on my previous Android game called Diamong Drift (no longer on play store since it crashes on newer devices and I can't afford to port it to newer game engine). I call this new puzzle Puzzle 4. The coding is going OK, but the design has not been settled yet. This is what it looks like during the past few weeks.
Diamond Drift was somewhat successful. Almost 100K download with minimal marketing. Hopefully people will like Puzzle 4 as well. Puzzle 4 is developed using Corona SDK so it will be available on both Android and iOS devices.
