ChuChu Rocket is one great puzzle made by Sega.
I've always loved the original, so seeing this made me smile a bit.
It's a great recreation of the game. The graphics are nice and puzzles were well-thought. Although I think some of them are directly taken from the original.
I know how to play the game, so I didn't really need a tutorial of some sort. But it would be nice to add a player's guide for newcomers. Not everyone is familiar with this game.
This game offers 22 stages, so it's enough content to keep you playing for a while.
This is what would I expect from a GameBoy port of ChuChu Rocket!
