If your goal was to make the mechanics feel good then you hit the mark. Connecting the plug to turrets and switching the colors feels good and is very intuitive to understand. The gameplay is alright, pretty simple and easy, but you have to be constantly switching plugs and colors to defend properly. I really like that there is a tutorial. The options button did not seem to do anything in game, but the menu button does work, also the music was much much quieter than the sound effects, especially the next wave horn which is quite loud.
