Don't Look Back- A Random Game of Much Stabbing (newgrounds entry)

EDIT: http://www.newgrounds.com/portal/view/599972?updated=1
There's the complete game. Future updates will likely only be bugfixes, I made this game without much rest, so editing the behavior is painful.

Cutting really close to the deadline here.

Anyway, here's a small demo of my newgrounds entry. Think of it as a hack n slash with guitar hero combat: http://www.stencyl.com/game/play/13884

I'd like some feedback overall, but my main question to everyone right now is: What should happen if you press a number key and don't destroy a block?

If you just don't press buttons, you'll die and do no damage, since blocking and attacking are not automatic. However, I'm not sure how I should implement an anti spam press mechanic, because right now you'll theoretically be able to kill everything by mashing the 1234 keys. What should happen? My current thoughts on what could happen:
-The player is automatically hit by the enemy, giving no chance to block
-The player automatically misses the next attack
-The player is not allowed to press any number key for the next few seconds

Which one does everyone think would work best?

EDIT: Is the music playing for everyone else?

I think you should get hit if you press a key at the wrong time.  Also, I don't hear the music.

That's weird, since the sound effects seem to play.

Whatever it was, a re-upload fixed it. As of now, mis-presses of the number keys will result in you getting instantly slapped in the face by your irritated enemy, giving you no time to react and possibly screw up the next key press too.

There's another game that goes by the same name, just thought you'd like to know.

Interesting idea.

And it's the guy who made VVVVVV too D:

I think I'll keep the (first part of the) name though, the two games have almost nothing in common.

There is only 1 level I want to play more

I'm posting the full version on newgrounds later today

EDIT: Just a heads up- the full version is also somewhat short, it was made in a week after all.

Tell me if you run into any problems!

Yeah, not as good as I was hoping for either.

Sitelock = uploads.ungrounded.net

How do I tell if it worked? When I preview, it always works sitelock or not :/

EDIT: Is it working? Removed sitelock entirely, nothing's happening for me :/

Yeah it's working for me now.

EDIT: If you die you can't restart unless you reload the browser.

Fixed.

Now with medals!
