Absolutely love this game, best app for the droid so far by a long shot. Only on level 6 so far, still working out my strategies; but to answer the question that's been floating around the thread, I found this on the Lupis Labs website:
"
What does the full version add?
These are the enhancements for the first release:
- 2 new maps
- Unlimited reward upgrades
- Unlimited difficulty levels
- The ability to get achievements like "Score 1,000,000 points in one game". These achievements are not technically locked in the free version, but the difficulty level cap makes them inaccessible."
