It is a super cool concept, I enjoied so much. The only thing is that I believe it is a bit too difficult. The enemies fire really quckly and spawn at a rapid rate and tere are times you dont have the time to react before you die. But it was not such an issue. I still enjoyed it very much. The controlls are great, the concept (I'll say it again) SO GOOD, and I also really liked the way it looked. Great job!
