Fuse is burning hot

Ok so I lied, it's not downloadable. It's Flash.

In this new game, you will solve puzzles by rotating the fuses until your plunger (the blue and yellow box) connects to the rocket. But that's not all! You must beat the clock and avoid bombs to complete each level. There are firecracker bonuses and self rotating pieces, and possibly some little leprechaun munchkins that have taken to cutting your fuse!

I'd like any ideas on new pieces etc before I start to build levels.

Many thanks to Eliyahu for collaborating on brainstorming the idea of this game.
