De Block - Game concept art.

If you're going to make it similar to Yoshi's Island, do not make it like the combat.

I swear gulping up enemies, to throw eggs, timing the shot, and then jumping up or down to get to the target is tiresome and annoying.

It'd be nice if you could shoot some sort of projectile the direction you face, like Megaman, if that's the combat style.
