Stickman Climb is a physics climbing game with a ragdoll rider: you drive up increasingly absurd terrain, and the character flops around convincingly every time you get it wrong — which is often.
Balance is the mechanic. Too much throttle flips you backwards, too little stalls on the slope, and the space between them is narrower than it looks.
Too much throttle on a steep slope lifts the front. Feathering the accelerator and leaning forward is what keeps the wheels down.
Yes — physics-based hill climbing with a ragdoll rider, in the tradition of the genre.
Yes — a light 2D game with nothing to install.
