Your job is to get the data frame to the exit of each level. The problem is that you have only enough memory to store two commands. That means you can either go up or down, left or right but not both. Luckily commands are placed in the levels and you can read them by moving the data frame over those fields.
If you read commands in the wrong order and get stuck, restart the level and try again (button or R).
This is actually my first entry that runs on mobile (tested on Android), whooo!
Controls
Click or tap the buttons to move (preferred)
X to move horizontally, C to move vertically
Theme
I did the Two Button Controls theme obviously. The only game mechanic I came up with that did include both themes was Snake. ;)
