Steps
1) Go into Jumping Dog [click link above to play]
2) Open cheat engine
3) Select your browser in process list
4) Click Enable Speedhack
5) Change value to ‘0.5‘ [OR lower if 0.5 is still too fast for you]
6) Start jumping. As the speed is slower, you can easily grab all the balloons and get a high score. Have fun.
