Played and Rated!
Really nice submission! I loved the medieval-themed chiptune music in the overworld menu. I thought it was a bit hard to grasp the concept at first but then I realized that level 0 was the arcade level - so once I got to level 1 and got the tutorial that helped a lot.
So I guess my feedback is that perhaps having the arcade mode as a clearly marked separate level would personally have eased my progress
Overall, really good job!
