Neat little mindbending game! It was a nice learning experience.
I figured out how to do it with only three buttons: 00, +i and *i. I used *i to rotate my character 90 degrees. Then I could use +i to move up one vertically. If I moved vertically, rotated 90 degrees, and used +i again, it's sorta like moving horizontally (or at least perpendicular to the "vertical" movement). So with those two I could reach any flower I wanted and If I got too far out I could just reset.
Nice job!
