This game is nothing more than a shallow ripoff of the much more challenging, entertaining, and original game Threes. The sad thing is that it was actually a clone of a clone, and the creator never even knew about Threes!
For the full story, read (or at least skim), this breakdown of the full events.
tl;dr don't support cloned games that are vastly inferior to their subject matter, and reward the innovative developers for the work that they actually did.
