Hidden

This game and the game 'Umbrella Escape' are pretty similar. For 'Umbrella Escape', the development team added explanations in English through videos. Anyway, for Hidden, you need to watch ads in both games to accumulate currency, and you need to collect over 25 to unlock the Mega Offer. You just play the regular game and then watch ads. In the Mega Offer, there are sequential message directives. First, it tells you to watch an ad and then install that advertised app. After that, you need to play the game or another app for a certain amount of time, achieve the goal, and then upload a screenshot as proof. Completing these 5 steps finishes Mega Offer 1. The Super Offer is completed after finishing Mega Offer 5, lol. I've only done up to the second to last one. The Super Offer takes about two days per Mega Offer, including administrator approval.
