When falling from gravity, the player falls "ladder". How to make a smooth fall?

Question

Unity

There is a player who is constantly moving along X. It hangs on the player Rigidbody2Dwith standard settings (non-standard ones don't help either). When the player is in free fall, i.e. he falls and at the same time moves along X, he does this with a "ladder" (pixel to the right - pixel down). Also, when a player jumps (like a bird in Flappy Bird), he also does it with a ladder. Player movement is implemented through transform.Translate. The camera is stationary.

PS The game is very similar to Don't touch the spikes for Android.
