Keys are the main thing. The gameplay requires you to collect golden keys to unlock the exit door in each level and i found that the jumping mechanics are quite precise for a 2d platformer. You must navigate through eight levels while avoiding red enemy robots and dangerous saws that threaten to stop your progress.
Start moving and jump using your keyboard to dodge hazards. You need to collect all golden keys scattered around the stage, then reach the exit door to finish the level. The red enemy robots and dangerous saws are the main obstacles you face, and quick reflexes are needed to survive. You must time jumps perfectly to avoid them and the exit requires the keys you find.
Inside the game, you use arrow keys or wasd to move and jump, which is kinda weird anyway, and these controls let you navigate the 2d world. You have to click or press a button to start the level, but the main action is jumping over saws and robots. Their goal is to get the golden keys and open the exit door. The game has eight levels that get harder as you play.
Quick advice: Always watch the robot patterns before you jump. i discovered that collecting keys early is better then trying to backtrack later. The saws move fast so you need to time your jumps perfectly to avoid them. Use the arrow keys to move and space to jump over the red enemies. This helps you unlock the exit door and finish the level.
Mechanics are simple stuff. You run left and right in a 2d platformer to find golden keys which are the main thing you need. The exit door is locked until you get all the keys and the robots and saws are enemies that block your path. You press buttons to jump and move, and the goal is to finish eight levels by using your reflexes and timing.
