Cool, liking all the actions the little guy can do. Especially the vegetable yank, I haven't seen anything like that in a long time. I hope all the different actions aren't too overwhelming.
Well, let's see, theres a jump button (most used), item button (boomerang, bomb, etc), ability button (fire etc), and grab/throw (R) button.
That might sound confusing but I'm really trying my hardest to make actions as intuitive as possible!
For instance, Brown has a sand-attack type move that activates simply when you turn around at sufficient speed, and a stomp move that is just DOWN in the air.
Climbing ladders, talking to NPC's, and entering doors is UP, for instance.
Grabbing ledges happens automatically, and then you simply jump to get up from the ledge.
You can customize controls as well, so that should help.
