Commands were pretty much removed once the game was released on Steam, now stuff like No Fail and Handsfree require extra work to getdo comands work in this version or not cause i tried and it didnt work so did something change or did i mess up something?
You can get No Fail in the store after beating some levels and saving up the game's money, whatever it's called. After purchasing it, you go to Extras, find the Modifiers or Mods section, and you can turn on No Fail there
For Handsfree mode, as long as you beat a level with at least a 2 stars rating, when you go back to that level (and difficulty you beat it on) there will be an option to press V to let it play handsfree. In this version, handsfree mode keeps the UI too, but there is a button you can press to hide the UI if you find it distracting or don't want it blocking the action
