Nice one @Jonnas!
I've played...
Wario Land: Super Mario land 3
I ABSOLUTELY love/ed this game!!
One of the best games on the Gameboy and I played it all the time!... however I honestly can't remember completing it!? (I'm not sure if I ever did), but I would go back and play levels over and over to find all the hidden treasure chests and hidden exits etc...
The hat's were SO much fun!!
The dragon hat... picking up an enemy and throwing it into the flames! :p The rabbit hat, and the bull hat... I just loved the concept, they were so much fun... Kind of in the same way the three different Animals were in Kirby's Dreamland 2 for example!
One of my favourite games from way back when for sure!!
Shake Dimension
This game is a gem and seriously overlooked!... which is SUCH a shame because IMO it's exactly the direction the 2D Mario series in general should be headed in for me!
Beautiful hand drawn animation, funny, original and fun boss fights, imaginative level design... Ships, Mines, Swamps, Casino's, Skies... it's more like the DKC games in this regard... not your standard boring themes!
I had great fun playing this and I'd recommend anyone to give it a go!
Great games!!
