To be fair i thought at first that this was going to be a Tetris game only with gravity, and physics.
But as i stacked higher up, realizing my stupidity that no mater how tight i made the gifts, the "lines" would not register.
Upon further realization that the height was being recorded in score i then figuratively face palmed, as this game was a stacking game, and for what it was worth it was fairly well made the physics are well defined with out being glitchy or annoying.
The music was well placed but forgettable, and the graphics where well placed.
Now the faults, it's quite difficult to program a physics engine, and to incorporate Physics's Eccentricities into a game that relies on predictability makes for a rather frustrating endeavor.
As well i felt with my plays that each time the stack fell, that it then became nigh impossible to advance any further, as the holiday themed blocks would no longer stack due to the physics and gravity, constantly pushing the blocks off the edge.
But as far as games on Newgrounds go its both fun and not too terribly frustrating, i almost have strange sense of humor as the blocks fall that although i know achieving a better height now was out of the question i just liked messing around with the gifts and seeing what gravity would do with them.
Perhaps this design might have been more at home with some other game? Other then a stacking game, or at least had the game be over once the stack falls?
