Metris Attack is a great name. I like it.
Ha.
Remember that game Pac-Attack.
I always thought that game had alot of untapped potential. Add a few more devices to that puzzle game, and throw Metroids, and Samus Aran into the mix and you got yourself a interesting puzzle game.
Powerups can even be dropped with pieces and you have to have Samus in her ball form roll over them.
Power Bombs can clear large areas of blocks and such.
Spiderball can allow her to move back up and around the path again.
Space Jump can allow you to press jump and have samus jump to another opened path.
Bombs can allow you to blow up cracked bricks to open up a new path.
It's a new genre. Puzzle-Adventure.
