How does your submission match the theme?
I understood the theme as creating a deep gameplay using limited input. I decided to explore the concept of a game where you can only move around, but depending on the direction you moved (and the order in which you did this) your character would trigger skills or combos (just like in a fighting game).

Choosing two times in a row the same direction would trigger one attack, choosing one direction and the opposite right after would trigger a different attack (with a different area of effect), etc.

I only had a couple of hours to make the game so I had to stick the basic and just implement one single attack, but it still serves to test the concept.

There's a walkthrough of every level on the game page.
