So, I like the concept overall, it's refreshing and it's fun; so well done, but, few things that could have been better :
add arrows as we don't all have "QWERTY" keyboards and also, I am on a laptop so I could not see 100% of the game view, and could not adjust that setting to fit my screen size. It can be easily fixed so, don't forget next time ;)
Very cool game otherwise!
