Yes! I love me a puzzle game with serious gameplay. You have created something which has a genuine challenge that asks you to carefully think through your actions.
I do wonder what this would look like if you could lean into it being a puzzle game. I think it might be more satisfying to play.
This game has a mix of puzzle and action elements. Many levels require you to both think through the right set of moves and also time your actions so you don't hit the red balls. I found myself somewhat frustrated when I had figured out the puzzle side but just hadn't timed the action side correctly, and it would have been nice to just focus on the puzzle side.
