Thanks for playing and recording! :-)
Judging by the gameplay video (and the sound playing in the video), it seems like you managed to open and run multiple games at the same time. Could you tell us how?
Update: Actually, I think I've managed to replicate what happened. Did you tab-out during gameplay? The game freezes when you do that in fullscreen mode. And apparently you can run multiple exe's of the game at the same time. That's why the audio was weird in the video.
Sorry about that, I've provided instructions on how to record the game properly on the gamepage. If you ever wish to re-record the game, feel free to do so. Thanks again!
