Here you load a bitmap and "grab" images 1,2,3,4. presumedly for level images

Here you are essentially wiping out your previouse reference to image 2 replacing it with a single player image.

So I am not exactly sure what you are trying to do with sprite 1. Sprite 1 is a single sprite that contains 4 images of animation. Not knowing what your bitmaps are actually of it looks like three of the frames of animation for the sprite is level images 4, 3 & 1; and only 1 frame of animation is a player image, image 2. Is this intentional?

I am thinking not because sprite 2 is using image 2 for the player. It seems to me you are overlapping and using image 2 for ttwo different purpoese. My suggestion is to first make the second get image command to image #5 like this:

LOAD BITMAP "player.bmp",2
GET IMAGE 5,2,0,45,4
delete bitmap 2

sprite 2,Nxpos,Nypos,5
