This game is short but very fun to play. I used a controller and it played very nicely. Good retro artwork. There are so many nice details in each room. The robots become more challenging as the game goes on with some intense boss fights.
Whether or not it is worth the price tag is really hard to make a call on; perhaps wait until it is on sale, although some of you may of picked it up in the Indie Rush bundle a few weeks ago, if that is the case, it's really worth a play through.
