This is a very very fun game! I played a few rounds and found myself getting lost in the combos and interactions. I am still not quite sure about how the timing of everything works - some aspects seem based on real world seconds while others seem timed off of the number of steps you take as a player - but it was a small enough thing that I was easily able to play and enjoy the game without understanding it.
With a bit of iteration, I could easily see something like this gaining cult status as a retro game on handheld devices. Excellent work!
