Jumping mechanics are straightforward but involve controlling jump power with your mouse, which i think makes the game kinda tricky and unpredictable.
Click and hold to charge up your jump, then release to leap over obstacles, which is a quick, simple process with a few secrets, like adjusting your trajectory by tapping during a jump, and it's all about timing, aim, and patience.
Inside the game, you use your mouse to control jump power, which is kinda weird anyway, and you click to charge then release to jump, their buttons are simple but effective for gameplay.
Fast and easy, i discovered that lightly tapping the mouse during a jump can help you adjust trajectory better than full charges, then avoiding obstacles like birds or blades becomes easier with practice.
Thingy about Jumper Rabbit is that it's a lazy, basic game with simple graphics, straightforward jumping controls, and an addictive gameplay loop that tests your timing and patience.
