tl;dr puzzle game with poorly implemented physics that doesn't reach it's full potential.
The concept here is good, but the physics let the game down as there is no way to distinguish between moving a block backwards, or upwards. The special blocks are also poorly balanced, and with only 15 levels this game is over very quickly. For the price, I would expect more than an hours worth of gameplay.
If the controls were refined and new mechanics introduced then this game would be in a much better position.
As it is, I can't recommend this game. I do hope the developers keep at it though, as there is potential here.
