Donkey Kong Country 2 was the first VC game I DL'd. And yeah it is a pretty tough platformer, it costs coins to save your game. I managed to make it to the last world but I can't beat the last few levels. Almost all of the levels in the latter half of the game will take multiple attempts. I don't know if it's harder than the first one though, I got about halfway through the first and it was getting pretty tough. I really liked this game though, it's a solid platformer and if you like platformers (which it looks like you are) then you'll like this game as much as I did. Enjoy.
