Great idea! I love the twist with how you play. I found out that with the enemys only being able to be on the path, you can hit them outside of the path with the knight, but it gets super hard quickly so you arnt able to do that mutch.
Thank you, Toaster with the Most-er! There is definitely room for tuning the core loop, the progression, and the difficulty curve. Lessons are being learned, thanks to wonderful feedback from people such as yourself :)
