Akari
Akari is a game written using JavaScript that is presented via the Canvas API.
Because it runs in your web browser there is no app to download and you can play it for free. I hope you enjoy the game.
How to play
To play Akari on your mobile device simply tap the screen to start playing and then slide your finger around to move the ship. On the desktop you can just use the mouse to control the ship. The ship will auto-fire. Destroy wave after wave of adversaries and collect the power-ups.
