This is what the Limited Shapes theme was all about! The way you used the limitation with the wireframe-styled graphics to get a 80's style atmosphere- great! Coding the enemy missiles as red always works :)
The gameplay was good engaging, but needs more polish. It would be cool if the game got more difficult the longer you play. When I lost (at 24 shards) I felt that with a bit more focus I could play forever, and the game would not defeat me.
The music adding more tracks the more data you have was really cool!
As for the theme- it took me a second to get that the data space was limited :)
Over all- it's a game that sneaks on you. You notice the graphics first, and the gameplay seems simple... but after losing the first time, you play again!
Keep it up!
