FrogJump

FrogJump is a platform-jumping game in which you play as a frog that leaves its comfort zone and finds the sea. Your goal is to keep climbing until you reach the boat.

You jump by holding and dragging the left mouse button, then releasing it. The drag’s length determines the jump’s height; once a jump begins, you cannot change its direction or height. A failed jump sends you back to the start. The author says completing the game takes about one hour.
