Tomorrow & Yesterday

Tomorrow and Yesterday is a time travel puzzle game. If you don't want any spoilers, don't read any further. The game contains only a few basic mechanics. Stand on an X to open a wall. Use keys to unlock doors. The most important however, is the time machine. By going back in time, you can work with your past selves to beat a level. If pick up a machine, and then go back in time, you will still be holding the key but you also wont have taken it yet. So there will be two keys. The levels quickly escalate in difficulty and complexity. Multiple time machines, all going back to different points in time, provide for a mind bending experience. When all goes well, you will be amazed by your own foresight and planning. And when it doesn't, the restart button will become your best friend. Controls: Arrow keys to move R to restart the current level S to sleep for 5 seconds. If you have a touch screen, you can also swipe in a direction to move.
