Great game, just as it should be.
I really like your game, I hope to see more originals in the future. A couple things people don't understand is that it's loosely based on the original super mario bros, and there were no health bars there. Of course, power-ups acted as them... yeah, some power-ups would be nice. Another thing is that the speed is fitting, I never found the Bullet Bills to be suitable speeds in the Mario series; they were always slower than bullets. Lol. I'm supporting you and making this a favourite flash.
