Fun and simple gameplay loop! Well executed. great job! 

The art is great. I think the idea was neat but it was a bit hard to handle. I had trouble understanding with the instructions. I thought the instructions meant it would be projectile when it meant the sword would slash where the mouse is. After I understood it, it was a lot of fun. I think difficulty needs some tweaking. Giving an easier pass on the lower waves keeps the player trying again. I did a lot better when just avoiding the bullets and not actually trying to fight the bad guys. It might also be cool to have like...a blue guy who doesnt leave but instead just moves around. This would give the player a need to have to kill the dudes instead of just avoiding them. I think its pretty awesome and I could totally see it growing. I like the noise when you get hit but a little music would be neat as well. Good job, overall.

I liked how you interpreted the theme, but it was a bullet knightmare, indeed.

Having a "shield" power-up could be cool here. It took us a while to get past wave 1; the difficulty ramp needs work.

Even with the description/instructions on the page, I was confused about how attacks worked.  I think having to hold the space bar to build up to trigger the attack is a little too much.  Being able to hover your mouse on a target and then hitting space as soon as you reach the spot I think would have worked better.
