Controls show up when you start the game. If you want to see them again, press "C". To start, press the "X" in the top right corner of the "Controls" panel. The objective is to find and shoot all 10 enemies. You have to reload after every shot. The smaller the scope is, the harder is to find all enemies. The game is more enjoyable in fullscreen, but in may lag.
Everything but the background is done by me, the background is downloaded from Freepik. If you like this project, pleas consider leaving a "love" and adding this project to your favourites.
