Euphonia is free on the App Store. Version 1.0 of Euphonia includes a tutorial walkthrough plus three games available via one in-app purchase. Version 2.0 introduces two new games with the ability to throw and catch a sound – Orb It and Soccorb. In-App purchase of all games is free for a limited time.
Walkthrough
The Walkthrough takes you gently into the world of Euphonia. You will learn to create the playing field, find the start point, locate the Sonus, and avoid a pool of boiling water. The intent of the Walkthrough is to demonstrate the immersive and unique quality of Euphonia’s audio-based augmented reality, and to verify a quality user experience is possible. If you enjoy the Walkthrough, and find it works for you, download the games!
Escape
Escape places you in a mystical maze of abstract obstacles. Your objective is to find your way to the beacon without colliding with any obstacles. When you reach the exit you receive a point and a new maze is generated. If you hit an obstacle, you lose a life. The game ends when your lives run out.
extra gameplay info:
Each time you escape, the maze is redrawn with more difficulty. Rest assured there is always a path to the exit. You may need to walk around a few things to find it. Be methodical and be patient.
Escape does not require you to move to the middle to start the next maze. It will be redrawn around you. Hold still to avoid walking into a spawn point during the respawning phase.
hints:
Listen carefully for the telltale hum indicating your are getting close to an obstacle. Take advantage of the pauses in the flute melody to note the positions of nearby obstacles.
Sonus Catcher
Catch the Sonus before it explodes. We like to imagine the Sonus is a virtual particle. Like most particles, it decays. When the Sonus decays, it explodes and you lose a life. Each time you catch the Sonus, a new one spawns. Each time you catch a Sonus, you have saved it from exploding. What a nice thing to do! If a Sonus explodes, you lose a life (and so does the Sonus…). The game ends when your lives run out.
Sonus Catcher tracks the distance you have traveled and the average speed as well as the time you spent playing, making it a convenient way to track how many calories you are burning while you’re having fun.
extra gameplay info:
Each time you catch the Sonus, the lifespan of the next one is shorter. The longer you take to catch the Sonus, the shorter the subsequent Sonus’s lifespan will be, so go quickly.
hints:
Listen carefully for the telltale hum indicating your are getting close to the Sonus. Hold still when you can hear it well so you can track which direction it is moving. Run where it will be. Be attentive – it will change direction and speed.
Murmur Mayhem
Take Sonus Catcher and add a nemesis, the Murmur. The Murmur is there to stop you from getting the Sonus. Fortunately, you also have a Zapper, which you can use to annihilate the Murmur. Be judicious – your Zapper has only one shot per charge. If you miss, you will need to get it recharged by catching the Sonus. If you successfully Zap the Murmur, you will gain a life up to your starting quota.
Add a friend to the game with Multiplayer Cooperative mode to watch your back. Two zappers are better than one! (developer note: this is an incredibly addictive scenario)
extra gameplay info:
The Murmur moves faster than the Sonus and less predictably. Over time, both particles gain speed. High scores are tracked separately for multiplayer mode vs. single player. There is a difficulty multiplier in multiplayer mode.
In multiplayer mode, both players must be standing at the start point in the middle of the field before the game will begin.
hints:
Listen carefully for the telltale hum indicating your are getting close to the Sonus or the Murmur. If you can hear the Murmur’s hum, you are close enough to Zap it if your aim is true. As with Sonus Catcher, hold still when you can hear it well so you can track which direction it is moving. Run where it will be. Be attentive – it will change direction and speed.
Orb It
Target practice. The target is on the north ‘wall’. Hold the device as you do in the other games. Flick your wrist (a soft shake of the device) to throw the Orb. It will fly in the direction the device is pointing. The closer the Orb comes to the target, the higher your total points for the throw will be. The farther away from the target you stand when throwing, the higher your potential score.
To pick up the Orb you may either walk to it, or press “Fetch”.
Add a friend to the game with Multiplayer Cooperative mode.
extra gameplay info:
You can hear a doppler effect on the Orb as it moves toward and away from you.
At higher difficulty levels, the target becomes smaller and smaller proportionally from edge to edge.
The game does not enforce turn taking. This allows the players to choose how they want to play. To pass the Orb from player to player, simply throw it to the other player. If the catch fails, the other player can immediately pick it up by pressing Fetch.
The player currently in possession of the Orb will have an Orb symbol next to their name on the screen.
hints:
The key to all the Orb games is accuracy – be sure to keep the device oriented well through the ‘flicking’ motion.
Soccorb
Soccorb is played like Soccer, but with the Orb mechanics. Once you have gotten accustomed to throwing and retrieving the Orb in Orb It, you are ready to try Soccorb.
Soccorb can be played single player against the computer, or two-player.
Difficulty level affects the skill of your computer opponent and the size of the goal (higher difficulty = smaller goal area).
The Doppler effect is a critical cue to understand where the Orb is going, and how quickly.
When the Orb is being held by a player, there is no Orb sound (the computer player has the Murmur sound).
If you get too close to the goal and shoot, you will receive no points even if you score.
hints:
Experiment with bouncing the Orb off the wall to try to score a goal (like Air Hockey).
The more quick the flick, the faster the Orb will go.
You cannot ‘steal’ the Orb from the other player (this feature is under development, though!), so when defending, your objective is to balance how close you are to the other player to cut off the angles available, and how close you are to the goal. The goal is wider than you, so standing right in front of its center is no guarantee you will block a shot.
