You control Yoshi with the arrow keys. Guide Yoshi through 20 levels and collect the fruits. Light Green is safe ground, Dark Green will push you back, Red will lift you up and don't touch Blue. There are three endings (based on your Happy Points at the end).
This is my first platformer. Sounds taken from @BobbyF_Extras Music from Yoshi's Wooly World. Yoshi belongs to Nintendo.
