Interesting idea that your genre without mechanic basically made a speed reflex game.

It's a good start but starts way too slowly - needs to have 10x the amount of beats to press

I'd say it also needs an added mechanic, as it's currently a little too simple. Good foundation though

The game is decent however I have a few issues. Firstly,  It's too simple. Try increasing the spawn rate of blocks or their speed. My other criticism is that music isn't core to the gameplay of a rythm game. What I mean is that if I were deaf, I'd see no difference between this and Rock band as opposed to how you'd really notice if someone ripped the shooting out of a FPS. Lastly, The moment I saw the game I really wanted a version where It's a rythm game but the songs are all terrible. I'm serious, put on your screechiest most annoying voice and go to town on a microphone for a solid 15 minutes and you have the game of the year.
