It's a neat little design, but that's all it is – and the execution is woeful. Three greeny-brown levels and then a 'Challenge' level that sees you playing all three greeny-brown levels in a row. A little more colour would have been nice. A game that didn't last just half an hour would have been nice. A half-decent challenge would have been nice. Some enemies that weren't can-based would have been even nicer.
