Honestly,I really like the graphics but the gameplay could do some work because right now its just clicking a button,maybe you could turn it into a tower defense game.

Nice work! The graphics are clearly the main appeal of the game. Gameplay-wise, it could benefit from better showing the paths enemies take, so players can more easily track their progression. It also obviously would feel more engaging with a higher number of enemies. Regarding the shock button, stopping enemies tends to make things feel a bit static. A push-back mechanic could achieve a similar effect while keeping the action more dynamic.
