Your task in this action game is to jump over the holes and reach the portal in each level to progress to the next areal. Use WASD KEYS to move around (press W KEY twice for double jump). Hold down "F" KEY and then look around using YOUR MOUSE. Stand on the switches to open gates to progress. Be careful though, they close quickly. You can use YOUR MOUSE to draw a line, which can be jumped on to get to the portal. Also you can hold buttons down with a line. Good luck!
