Wacky Flip is the best place for you if you love extreme parkour but are scared of being hurt. It's a skill game that mixes gymnastics, street parkour, and a very realistic Ragdoll physics system in a way that isn't obvious.
How to play Wacky Flip

In Wacky Flip, fast typing won't solve the problem. The only key to winning is rhythm.
The Four-Rhythm Formula
Crouch: Press and hold the mouse. The character will bend their knees to gain momentum. The longer you hold, the more the spring force will change; time it perfectly.
Jump: Release the mouse to launch the character into the air.
Flip: While in the air, press and hold the mouse again to make the character roll over.
Land: When the roll is complete, and feet are pointing downwards, release the mouse to straighten the character and land safely.
Tactics
At the early levels, you only need basic jumps. But when you move to areas like the Construction Site, the height difference between the jump point and the landing point will be huge.
Observe the distance carefully before taking a run-up. For long distances, click and hold longer to perform double or triple flips. For short distances, release the mouse quickly to avoid overflipping and hitting your head on the ground.
Multiplier
Wacky Flip highly values continuity. Successfully performing consecutive jumps without falling will increase your Multiplier bar.
Don't just do one boring flip! When you unlock new skills like Pike or Knee Tuck, boldly combine these moves in a single long jump. Showcasing your skills in mid-air will help your score explode impressively.
