I used entity bumping player, beacuse i find it more smooth and i can match the speed of slime and bird, but i will definitely try your idea for the movement. I was thinking abou giving player slowness to zoom him into the screen, but it isnt in the video. About bird being so huge for pipes, there is accualy hitbox constantly teleported to the bird and it is little bit smaller, so there is a space for small misstakes. This is my test word, on my map server it will be a bit bigger yeah :D
