I probably should have gotten around to this earlier, but following the responses to the game, the biggest complaint was the slower progression, causing the game to feel like a grind. So the multiplier used to increase the shield size has been reduced, so less data is needed. And, while I was at it, I built the game for mac, so more people will be able to play.

Hope you enjoy, and thank you for all the replies so far,

Chris.
