Killer kill

You have two games , protect the beacon and scoring game (just have the best score). Its only the first version ! You can attack with space and moving. The 2nd player plays with a controller and attack with A (and X with a Ps4 controller). Ill maybe update this game but i dont have ideas so can you give some ideas to me ? And its a game made in 17 hours (i has 24 hours but i dont have more ideas now)
