Yeah not bad
For a madness flash, a genre which has been done to death, this was alright. You obviously show plenty of skill and if you continue, you'll only get better.
But why not turn your hand to something original? Again, you obviously show you're committed enough to make a flash, so why not something of your own?
Just a thought, that doesn't detract from your score.
The music was fitting but my only gripe is with the intelligence of the 'bad guys'. Some came running out and just waited to be killed. It detracted from the believability of the flash.
Keep up the hard work.
