Well done - the AI destroyed me over and over but that matches my usual performance in Smash Bros lol. Music and assets were great, also I really liked the extra sugar with the nice scene transitions.
Small note: I do not have easy access to a Windows machine right now, so I ended up playing via 64-bit wine on OSX. It was a bit wonky to get working, as it's not something I ever do, and there were a lot of 'untrusted developer' warnings I had to click through. It eventually launched and I could enjoy the penguiny greatness :) A built .app package for mac users would be an awesome touch!
