Hello,
You did a wonderful job, congrats on the game you made. It brings be back to flash game days on Miniclip. I think the gameplay loop was easy to get and understand and maintained being fun throughout. Good job implementing difficulties levels as well. I think that the music gets repetitive pretty fast, could be good to find something that is a little longer before it loops. The gameplay loop is solid and is polished well. Hope that you continue to refine this project and maybe release it on phones!
