Save the Princess Question Mark

What about all the modifications to the interior?

Tiny Castle is Nitrome's latest delicious super-pixelly browser-based gaming mini-meal. You play as the above pictured Knight making his way through a castle wrought with dangers in order to save (?) the Princess!

By all appearances Tiny Castle is a single-screen platformer, but thanks to an angry Grandad (Wizard?) the playing field is constantly shifting. It's a really neat mechanic that I'd love to see executed in a "full-fledged" game with more levels, which I'd happily pay for on PC or the various console download services.

Anyway, play this gam, it's super tiny.
