Nice concept and I really liked the art and sound but I think the gameplay could use a bit more work, also there's a bunch of bugs that kept kicking me out of the game. 

I uploaded the play through of your game on my channel, check it out.

Gameplay is cool, but it would be better if you could speed up the process.

love the music ;)

Great art and great music! The game is really cool, unfortunatly, like the others said, I was focused on the arrows and not on what was happening in the middle of the screen
Great game!

At first I didn't know what to do, so I was frustrated with the game over when I was hitting all my keys! Turns out I needed to time the keys with the situation on the left.

Sometimes the timing of the keys could be a little nonintuitive, since I had to look back and forth between the left and the right. But had fun nonetheless!

Awesome

Awesome concept! Like others have said, only issue was focusing on the buttons and not seeing what was happening with the zombies. Great music and art!

I really like this game but you should modify the easy level because it is a hard level ahaha. All my attention was on buttons and I wasn't looking at the  zombies at all,apart of that it is a very cool day.Good job!

I really like rythm games and this one went pretty cool! Good job!
One interesting thing is that all my attention was on buttons, so I wasn't look at zombies at all, idk is that a problem, just my experience.
And the music fits nice)

Just read that this was your first game and I'm pretty impressed! The controls can be a bit tricky to get used to, but all in all a very fun concept and reminiscent of old DDR games with a twist. Well done!
