I liked the graphics, minecraft-style, hehe. It's a fun little game, requires some skill but once you get the hang of it, you become a sorting machine, haha. Simpe and creative mechanic, nice theme, nice music. Overall pretty good game! I wish it wasn't that long though, or maybe have levels in between so they slowly ramp up with the difficulty. Remember to have exit points for your players. Keep it up! Meow!
