XPortal Dimensions app for iPhone and iPad

For an unknown reason, the parents of "H" have died. His absence created in him an obsession to see them again, so he created a machine that showed the possible alternatives of the future, as the case where his parents had not died. Due to the immense amount of time invested in his project, he neglected the only person who was in his life and needed his attention, his younger brother. An energy imbalance opened a portal to another dimension, dragging "H" into it and leaving his brother more alone than ever. Now "H" will have to look for the way back home.
