While it's easy to dismiss Ruff as a poor man's Ratchet, there's more to it than that. While most games that sell for $20 new are almost without exception cheap junk, Ruff genuinely seems like a bunch of people got together to earnestly create something really cool. They were tripped up by cost and time concerns, but their intentions were good, and they even stuck in a bunch of motorcycle levels Piglot-themed minigames for players to unlock.
The design isn't too shabby, either. Stick with the game past its irksomely bland early levels, and the game comes into its own with more interesting weapons, levels, enemies and objectives. Even the useless Piglots get smarter, with a few of them able to clear debris (by exploding) or open doors that you couldn't otherwise get through.
