Delve into the world of Shimmers! In this cosy indie game, you hop through time and space to meet different unknown Shimmers. The Shimmers you meet could be anyone from all of human history, fiction and folklore. It's up to you to talk to this unknown Shimmer, and to use up to three open questions and guesses to slim down the infinite options to just one. Be careful though: Shimmers are slippery and cunning, and will flee to never be seen again should you guess wrong too many times. In addition, you only get one new Shimmer encounter per 3 hours, and can only save up to 5 encounters. Make those guesses count! Each Shimmer will have a unique rarity, as well as unique traits. Some Shimmers may even have unique emotions that will seep through in everything they say. Once you have found and identified a Shimmer, you add them to your Temporal Codex for safekeeping. Are you knowledgeable and nimble enough to meet and identify all Shimmers? Shimmers+ Can't get enough of playing Shimmers? Subscribe to Shimmers+ to drastically increase the amount of Shimmer encounters you save up (15 instead of 5), increase the rate of new Shimmer encounters (a new encounter every 1 hour instead of 3), meet unique Shimmers only available to Shimmers+ members, and enjoy an experience without any ads. Why a subscription rather than a one time purchase? Because keeping Shimmers in the air requires running costly servers now and in the future. We are so thankful for your support! IMPORTANT NOTE: the Shimmers (persons) you talk to in the app are not real whatsoever, and are modeled by AI algorithms.
