If you didn't play it the first time I posted about it, it's going to be on WiiWare for 1200 points now. (Or you can play the free PC version.)
If you didn't trust my review of it, IGN gave it an 8.5 out of 10.
If you aren't planning on playing it, and you've ever liked any given platformer ever, you are seriously missing out.

1200 points is annoying, given you can only buy in 1000-pt increments. I totally agree. That being said... Super Metroid is 800 points. I see a very obvious purchase path for this.
