This was fun and very original! I found it quite intuitive as well. Yes, you don't really know how many steps it will take the first time, but once you pass the first level, it's not too hard to guess. Making it a bit faster and improving the visuals (especially for the character) would be great! Also, being able to clear your input before running the game would be cool. As a side comment, if you press an invalid combination of keys (pressed A + D at the same time by mistake), the default UI's "New Text" label appears. Needs some polish and more exploration of the mechanics, but the concept is really cool!!
