Could someone please give a summary of the game play and what makes it hard? The description of the game doesn't reveal much. (not able to try it at the moment)
This is a puzzle game in which you're able to slide objects (one penguin and a few ice blocks) around a 5x5 grid. The objects will slide off if they are not stopped by anything else, and the goal is to get the penguin to a waterhole in the center of the grid. It's difficult also because you get limited number of moves on each level.
I just started playing (on level 3) and it's difficult for me because you're not only sliding the penguin but also the surrounding blocks. It makes it harder to plan moves ahead..
