If you honestly want my opinion...
They could have been better. I personally think it's cool to see people still experimenting with ideas in the 2D as long as the gameplay mechanics are fresh and the graphics non-primitive.
Both games seemed to exhibit a unique concept, but Twinz was easy to beat and I tried to play MWB twice before I decided that I couldn't catch the jist of it and the music was solidly annoying.
However, on the positive note, I really like your avatar (ARNOLD FOR GOVERNOR!!! even though I'm not a Californian).
