Carry Eist through the boards, placing arrows on his way to indicate the direction. Descent from the path will make him fall down. You must pick up all artifacts for the exit to open. Along the way you will meet doors: you need a key to open each one. Use the ladder to cross gaps in the path. It can only be set in designated places. Touch the ladder to pick it up and set it where you need. On some boards you will also meet teleports: they move Eist to each another. Remember: the movement direction stays the same.
Compete against other players on Google Play Games leaderboards (assigned to each level and the total score). You start each level with 10.000 points. Every direction change takes away 100 points. Eist's movement takes away 1 point every each board frame. Select the shortest path to save as many points as you can. Every few boards there is the opportunity to collect extra lives.
The premium license (in-app billing) will allow you to save the game state on demand (e.g. before starting a difficult level).
Each board requires (really!) careful planning before you touch the screen for the first time, and put Eist in motion.
Original version of the game was developed in 1992 for 8-bit computers. After years, written and drawn from scratch, it gets to Android tablets and phones, and also to Android TV and Chromebooks.
If your device has the touch screen, it will be the default controller. Otherwise, the game will allow you to select between mouse and game pad, and the speed of the movement will be adjusted accordingly. Although the application is fully gamepad-ready, even in the case of Android TV you should consider using a mouse, that will accelerate and simplify the gameplay.
