i played on timeless level. hints given by game. this game has invisible tiles that will have to be made visible (by making a match next to them or an arrow) to finish a level. this got me a few times then i would remember this.
i played on the custom level. good hint system. there is an institution that was opened by a dr. to do experiments on humans for the benefit of others. it causes the people to lose their souls. you are trying to reverse the one you can.
i played on the custom level. good hint system but some of the scenes were too dark to make out the objects you need. an entity has overtaken this woman's sister and she is trying to set her free.
i played on the casual level. good hint system. it is about an enemy that collects humans in order to live. he gives them a choice of becoming one of his soldiers and accept his dark pact and become a puppet for him or die. he took your sister and you are trying to find her.
i played on the custom level. good hint system. it had a shape shifter enemy. it was capturing people's essences to live forever and increase it's power.
