Giddy 3: The Retro Eggsperience

The world is under attack from robot stompers from beyond the clouds. As Giddy - the No.1 egg-shaped super hero with unfeasibly large hands - its up to you to save the day. Apparently, this involves exploring some oddly connected scenes populated by wibbly characters to find items that when used correctly, make things happen (generally toward said "saving the day" objective).
Trundle about the place avoiding the enemies, if you wander past something interesting, a flashing lightbulb will appear - you can then press the "Clue" key for some advice if you need it. If you've collected something that you think is appropriate for the situation, press the "Inventory" key and cycle through the stuff you're carrying ("left" and "right"), then press either "Jump" or "Inventory" again to try it out. Remember you have to be near enough to the problem (look for the aforementioned lightbulb) for an item to work, if indeed its going to.
As well as puzzle-solving objects, items of energy-replenishing food are dotted about the game, which can be useful as the wildlife can be none too friendly (you cant kill 'em - what d'ya think this is, Resident Evil? As you may notice, your energy level is depicted by stars next to Giddy in the top-left area of the screen.
