WASD to move around. K to shoot a normal bullet. L to shoot a stronger bullet that deals more damage (with a short cooldown). When your score reaches 30, a boss will appear. Destroy the boss and you won the battle. (If you want to skip to the boss fight just press M, it will increase your score by 10 instantly, the fight before the boss is kinda boring imo XD)
Boss and all the attack effects were made by me. Player's and basic enemies' mechanics made by my friends. This was a rushed project sooo... It isn't that well polished yet. My apologies!
