The mention of the lost PMD webgame last thread reminded me that the Explorers of Sky promotional website used to have a Flash version of the footprint sentry duty minigame.
I thought it was lost forever, but I remembered that Flashpoint exists and sure enough it is preserved there.
For some reason the sounds don't play for me until I play through it once and click on the Reward button.
I remember that you could download a Sky-themed clock widget from the Sky website, and I think that might have been the reward from the minigame. Unfortunately the widget doesn't seem to be included with the preserved minigame.
