Congrats on being the top rated game in the jam! Best presented too, it seems.
EDIT: Having now played it, I could easily see this being a complete game. There are so many ways this could be expanded. More actions, such as jumping, firing a gun (so you can hit distant enemies), or activating a switch (think the on-off blocks in Super Mario Maker); more stage elements, such as enemies with more life, ground tiles that crumble, ice blocks that you slide on, or teleporters; or many other things I can't think of now.
It reminds me a little of Baba Is You. Not quite so brain-bending, but still a tile based puzzle game where you have to plan out your movement carefully. And that started life as a Nordic Game Jam game, so...
