Alien Turret

ok this is a game I am working at as a solo dev, but its now starting to get at a point that it needs to get some external feedback, and if i am lucky, some extra team members so i have a chance to finish this.

How it works (no tutorials yet :-): Using the mouse: Merge more than 2 tiles of the same symbol with a target tile, to shoot a lazer, the longer the better (longer lasting lazer). Link more than 2 tiles of the same symbol to merge them to a higher symbol. Use power ups that you get slowly as you play. To win a level, you got to kill all enemies
