This game needs a complete over haul. Firstly include an option to change the controls, secondly no re-spawning enemies because nobody like them and they are annoying, furthermore include auto reload because nobody wants' to waste their time reloading and finally include some power-ups because power-up will be handy in this game. Over all the game is a good idea but it needs improving.
Unfortunate on the unresponsive character but bonus on finding the game confusing! Thanks for checking it out.
