Fun at first...
but after a while, it got sort of repetitive, but I didn't get very far...maybe it changes a bit in the later levels, yeah, anyway, it was great fun whilst it lasted, the graphics were awesome, the actual idea is pretty unusual (in a good way) as well...
Just try make the beginning levels more interesting so you can keep us easily bored jerks satisfied for longer =P
Overall though, it was a great game =)
