Hey, Mike here. 😺 Thank you for making this demo. I agree, I also perceive gestures to be underutilized in games so it's exciting to see that you created a game with one!
Specific to this demo, I think one of my issues is how the camera also moves when you make a gesture. This made the game too "shaky" in my experience. Personally, I would like the camera to walk with the character so that doing any gestures would have a steady camera.
Overall, I was quite surprised I enjoyed testing it especially when the song started to play. I felt like the character was in a movie and it's time for his epic battle sequence. 😁
