I'll keep this short. Not because there isn't much to say — because saying too much would ruin it.

On the surface: you control a dinosaur, you're trying to take out the other dinosaur standing in your way. Simple enough. Then you look at the keybindings.

Each level gives you a set of commands you can customize and combine. Two upward moves collapsed into one input. A single button that goes up then immediately down. It sounds like a small mechanic until you realize what it opens up - movement combinations you wouldn't think to try, angles that shouldn't work, moments where you figure out a solution and feel genuinely clever for finding it.
