the 'ball' seems to be football shaped to an extent. When bouncing on a flat surface, it will occasionally stop and roll the opposite way without hitting a wall...
If you think 25 is hard you just suck at pong... I did it on my first try and thought it was quite easy... just keep the ball between the top and bottom paddles.
Easy exploit for infinte cash.
Start a new game. Build a palace and a market. Right click, click forward and then right click and click back. You now have unlimited bonus points. Go to the market and spend them as you like.

Stop your complaining about level 4... Level 8 is about 10x as hard... for level for you just have to distract the heli's with tanks and have a lot of bazookas to take them out.
I got through using just gold nail and artillery as my only upgrades. I focused artillery on the land guys only. Use the respective weapons on flying enemies. Dont let your ship get damage too much, I finished with 82 hp left and never repaired my ship. I got the island on day 10.
