People may recall that
Nin²-Jump was released on XBox Live shortly after the 2011 Tohoku earthquake. Cave, the developer, donated the proceeds from all sales for more than two months after its release to the victims of the earthquake through the JP Red Cross.
Although Cave is best known for its difficult bullet hell games, Nin2-Jump is a platformer (not a shooter) and is relatively easy. It has simple controls and is best played with an arcade stick (IMHO). It's easy to get hooked on. If you don't have it, it's only $5 and, now, as a BC game, it can be played on both the 360 and X1. I highly recommend it--you will enjoy it and, if you buy it, you will be rewarding a company that has a generous heart.
