I need to develop a game in assembler

[Alex0701]

excuse me for my bad english, I'm from russia. I need to develop a game in assembler8086. I am student of KOMSOMOLSK-NA-AMURE STATE UNIVERSITY. I have a bad programming teacher. Can you help me with my problem? I drew a drawing for the game,but I can not go further. I need to implement the movement of the ball and its jumps through rectangles. Its easy game, but my teacher can*t help me. I need your help, please.

What I have tried:

code segment
assume cs:code, ds:data
jumps
begin:
mov ax, data
mov ds,ax
mov ah,0Fh
int 10h
push ax
mov ax, 0013h
int 10h
;==========


mov ax, data
mov ds,ax
push ds

mov Rectangle_X1, 45

mov FillCircle_X, 25
mov FillCircle_Y , 140
mov FillCircle_R, 10
mov FillCircle_Color,55
