If you don't have a cheat engine, you can still make changes to money and other things, you just need to go to
"REGISTRY EDITOR -> computer -> HKEY_CURRENT_USER -> SOFTWARE -> SupaShinken -> Handyman Legend"
then look for your save data starting with the letters "SD ", If you save in the game in slot number 1 then look for the name SD1, if slot number 2 then look for SD2, then select "modify" inside look for the word "m_money" then change the number behind it for money, for HP look for the word "m_energy" then change the number behind it, if so you can click "OK" and continue your game, I hope this helps
