Good start, the prototype has nice ideas that you have to polish. I notice some issues with collision with the tower. Also the animation of the player has to be improved, you can setup 2 sprites in each direction to give the idea of movement. Also without sound and music is missing the atmosphere. you can find some free music on internet.
My game is a casual game if you wanna rate is https://misterm.itch.io/mixtape-match , Thanks
