First, there’s the colour-switching. Platforms are either yellow, pink or black. Land on one while the wrong colour and you’re dead. Land on a black one while any colour and you’re dead. But time it right, switching colour just before you land, and you get a little speed boost, the importance of which only later becomes apparent.
Secondly, Chameleon Run isn’t so much about survival as choreography. Instead of presenting yet another algorithmically generated auto-runner, the developer has painstakingly designed and refined every step of this game, and you must commit them to memory to have any chance of success.
Fortunately, you’re regularly taught new abilities to help you survive, such as double jumps and head jumps (essentially, headbutt the platform above, giving you another chance to avoid tumbling into the abyss). New obstacles also occasionally appear, although they’re not always advantageous — fans will usefully fling you into the air, but land on the wrong bit of a see-saw and your momentum will be abruptly obliterated, and you’ll battle to avoid falling to your doom.
