Nice game!
The design was pretty interesting. I'm the kind of person who is willing to not just look for a lot of great graphics and a lot of stuff going on, but more about how fun something is, and the ideas used. It was very fun to get those little things and step on those blue whatever-they-are. While it was difficult for me to find the secret areas, I think the biggest complaint was that it should have been longer. I think that this is an idea you could really go places with.
