Glad you like 'em! Shall I add the Terminator to our stock smilies, you think?

As long as you've chosen the easier mode to play on, you'll see a ? in the bottom right corner of the screen:
You can see that there are four Roman numerals there. That's because there are four hints! In the opening scene, you'll see this as the first hint:
You can't see from my screen above that the hint is animated, showing you that you need to grab the cage and swing it from side-to-side. Sometimes if you wait, additional visual aids will pop up as part of that same hint. You can make it go away by clicking anywhere, if you don't want to see any more.
Hit the ? again to see additional hints. If you want to look at a hint again, simply click on the Roman numeral indicating which one you want to see.
This isn't always going to be helpful! You may know that you need to do x-action, but you may be incapable of doing it! Keep looking around and experimenting, and eventually you'll figure it out.
