Just finished my entry. Scope was a lot smaller this year, so it's feature complete, and (reasonably balanced). I've beaten it at least once, so it is possible.
The premise is that you cast spells by moving in specific patterns, thereby making positioning extremely important. Other than that, there's a bunch of spells and each enemy is fairly unique. As apparent from the gif, there's also some freaky stuff going on with the tiles.
You can grab it here.
Hope you enjoy.
