Title art is cute and your interpretation of theme was very unique!
While the game art was basic, it was consistent throughout, and that helps out quite a bit. The gameplay itself was unique with the character swaps, but moving around and shooting was sometimes janky. Sometimes I felt the character who shot the ranged attack would not shoot for some reason.
Some small critiques would be to add music/sfx, a main menu, and a level restart on death. I played through twice but died on the 4th level. It’s tough to have to go back to the very beginning.
Overall, unique interpretation of the theme and great work on the game!
