Perfect entry. Game is fun, fits the theme pretty well (so far, it's the only game I've seen where combining can be good or bad), very intuitive (I didn't have to read any instructions apart from the controls which show up on the screen. All the boxes did what I expected), the sprites look perfect for that type of game. There's always room for improvement, but I think this game could be released with very little touch ups and more levels. If you plan on making a level editor, make it available for players.
