Yeah it's a mini mushroom. This was really to show the concept. It could easily be changed to suit the world and difficulty. And you could put a power up if you wanted I guess you would just never know. Or a 1-up to replace green houses Star for Star houses and so on....
Feel free to use this as a template to make your own.
It could be useful for several reasons. First, the game is too easy. you already get extra coins for using fire power, start with 2 more men, and get to save and continue: this eliminates, or at least makes it more difficult to make it even easier by powering up between levels. I personally would like to have the game as challenging as it could be. It makes you get those coins and break bricks because you need the 1-up. You don't want to die, so you take your time between levels.
I'm sure anyone playing this is pretty decent at this game.
I'll test it and post it soon.
