I don't know the language which the game is on, so i can't do a lot.
However, is a web-explored based game or a flash game?
If it's a flash game I think u can edit values with Cheat Engine by searching for the current value * 8 (multiplied by 8), and then editing it for ur value * 8. Or if it is flash based u could also do a vb6 "hack", by using a shockwave control.
