played quite a bit.
it's pretty good.
it's a 2D exploration type game so yeay, like Metroid.
the game focuses more on exploration that action so your offensive capabilities are limited. You can jump & stomp on enemies to kill them, and sometimes theyll drop an item which u can pick up & throw.
later on u get an attack, but u hafta charge it with each use, and you are idle during charge.
you can rescue your friends who all have different abilities to get you thru areas. My first friend can traverse ice areas and swim over water, my 2nd friend can jump longer distances. I think my 3rd friend when I find him lets me swim underwater.
the game is password based so either write down or take a pic of the password which u can access via your crystal ball item, or just use Wii's save state feature.
I also found the map & compass which shows where I am. In addition to the previously mentioned item that lets me attack, I assume many more items are to be found.
when you die u continue at the very beginning. so there may be a lot of step retracing, but the game can move rather fast.
graphics and art are fantastic and very colorful! Music is ok, not bad but not amazing.
I'll definitely be playing it a lot til I finish it!!
