Well the mechanic was the first thing that came to my mind so i just made it. It was like "Hmmm... "only one" what can we do with it... Well i make a ton of shooters..! Well its not gonna be very original but oof it!". And i made it. Also the game might feel fun cuz i put a ton of effects in there (also i watched a video on how to make your game feel good so heres that). Dont forget to rate!
