The game is a platformer/puzzler hybrid, combining quick reactions with smart thinking. It was originally released at the end of the GBC's life (In 2001) and was met with pretty positive reviews from a number of sites due to it's simple but highly enjoyable gameplay. We suspect that both the US and Europe will get it as WiiWare launch title.
This WiiWare upgrade is looking really good, and we personally think it's great that we're getting so much 2D game on the service. Two Tribes has also revealed that with a second Wii remote, you can draw on the screen. The new screenshots have been added to the game's page.
