The Game - Don't lose it
Pro-Tips. How to beat the game in under 20 days:
Your first 3 throws aim high. If you can't purchase three power-ups in your first two turns, start over.
After that, give some really hard throws, but keep it fairly straight and under 3 meters. You'll get a really good velocity bonus giving you extra meters (and ultimately points) Once you upgrade hurricane and have navigation controls you can keep getting a boost off windmills. 10, 20, 30 at a time. Don't be afraid to pull really far back on your plane to keep its momentum to reach the next windmill.
Purchase Lightweight/Aerodynamic upgrades first followed by the ability to steer your plane. Always choose to upgrade your plane over other upgrades ("Better Model").
Use Rudder Control to bounce off of windmills. Once you have enough money, upgrade Hurricane and crane booster as fast as you can.
Don't ever purchase any upgrades from the bottom row except Crane Duration (after you have passed the first 1 or 2 levels.
Remember: To clear a stage you must go for distance. Conveniently this is also the best way to get points. I'd know. I've spent just over 16 hours playing this game.
After you've reached the third stage you should work on upgrading Lucky Star and Green Fuel.
Throwing Power and Fire engine I did not mention so far because they are not very important to upgrade after you upgrade them initially. These are your 1-and-done power-ups.
I hope it helps!
