This was a lot of fun for a demo - I'll admit to setting a few bombs off intentionally - and I hope you make it on Steam Greenlight - I voted! I'm looking forward to more challenges.
Have to agree with the user that brought up the camera rotating with the mouse - it's a bit too herky-jerky for me.
I did a video, if anyone feels like watching: https://www.youtube.com/watch?v=Tl60m7M34SM
