Preface

This is a sort of incomplete port of mono, which is a really great and fun free game. This version lacks much of the more advanced parts of that game, because I ran out of time when developing it. You should play the full game instead!

Missing features:

  • Enemy shots
  • Enemy Robotron behaviour
  • Screen wrapping
  • Screen effects

Does not work on a real Master System, or on accurate (and inaccurate) emulators. Sorry!

Story

You are a white circle. You shoot bullets all day long. You wish the world were more white, like you. But it is all black. This makes you sad.

One day, some evil coloured circles started appearing around the edges of your world. When your bullets hit them, some of their colour fell off onto the ground. When your bullets hit them some more, they split into two smaller circles! And when you shot them, they split too! But the tiniest coloured

circles didn't split, they just ran out of colour and disappeared.

As you idly blasted them into oblivion you noticed something surprising: red, green and blue colours could mix to produce others! Red and green made yellow, red and blue made purple... and when you had enough of all of them, it made wonderful, glorious white! This made you happy.

So you took on a new mission: turn the world 100% white.

Controls

Button Action
D-pad Move
1 Shoot further anticlockwise
2 Shoot further clockwise
1+2 Shoot in the opposite direction

Disclaimer

I realise the story might sound somewhat racially charged if you were prone to read unnecessary things into an innocent pile of crap story. So don't.
