Arrow keys to move. Water makes you drown. Get to the apple to advance. Press R to restart. (This will be helpful if you get stuck in the ground it happens) Also, Please don't go off the screen. Yoshi will get tired if you jump without moving, so don't do that (you can if you want, though). EVERY LEVEL IS POSSIBLE
10 levels so far, more coming soon! Thank you @toadette_toad for helping me with some code. If you get no deaths, put it in the comments. I will give you a love and favorite to ALL of your projects.
