Remember Gero Blaster, the new frog-platformer from Cave Story's creator? It's now called Kero Blaster, and it's coming out on PC and iOS on May 11. There's a nice pixelly trailer for you above, in case you wanna have a closer look.
So how does the WiiWare version of Cave Story stand up to the original? I couldn't tell you, as I've never played the PC version.
