I really liked the game, easy to understand goal and mechanics that should allow you to make quite interesting puzzles. The levels (so far) also required some planning and where small enough that you could walk through the needed steps in your head without problems.
The only 2 problems I had are that it gets a bit annoying to constantly need to press a button to walk 1 tile, some way that I could leave it pressed and keep moving would be appreciated. The other problem was that it was too short (which, for a game jam is actually a good thing I guess). It ended exactly when I was getting into it :(
