Well, as others already noted. This is more of a visual show than a game.
Even more so that often clearing a stage is a matter of luck, unless you got supercomputer brain able to calculate every trajectory and collision with included vector changes after each explosion :P
well, was still somewhat fun to play.
If I might suggest, implement quick restart button or something. Like space/enter to reset the stage, so we won't need to use the menu from the top right corner each time. (extra lazy option)
