Good Concept
The gameplay was pretty fluid, except maybe the controls could use some rearranging. It was challenging and fun at the same time.

Not Half Bad!
Very nice concept and you implemented it pretty well!
All it needs is slightly smoother graphics (they feel a little cheap at the minute), a little work into the animated gates and buttons (making them move a bit more realistically) and some sound effects would be welcome.
I really enjoyed this and look forward to the next one!
