This app is a bit of a disappointment. The created tiles are generally red, though I had one appear in yellow. For example, when I typed in, "move 10 steps (which is a blue tile) it made it in red and almost always does the same with other commands. Frustrating and destroys the usefulness of the add-on for classroom instruction, which is too bad because it could allow for the easy creation of instructional slides. The tiles are adjustable in size, but the color of the tiles are not reliable. Please fix this! It could be a great Add-on!
