Had to quit when my fingers got sore.
Nice and original, but you need to adjust the level dificulty and lag.
I liked the music. You should look into changing the rate of blocks to the music tempo changes. That would be cool.
I played twice and only quit when my fingers got sore each time. never was in jepardy. It seems to get easier after level 18 or so. I quit at level 39. My strategy was to stay close to the floor near the middle and just keep firing blocks down as fast as possible that kept everything pretty slow due to all the explosions flying around. Then I just get the slow moving top blocks from the bottom. Nice work for 2 days but you might want to give it a week next time. That's still 50 games a year. :)
