There's really no reason to touch balloons at all except for the achievements. It's way more fun and relaxing to just throw bombs into each other and upgrade the coin drop rate and value.
Ok, someone here on the comments lied. Nothing special happens after 4000 m.
Also, randomperson2 i think he's trying to avoid those giant walkers in the background that shoot lasers at the ground.
The windows are like ten steps of difficulty harder than the whole rest of the game.
Oh and crashing into two boxes next to each other is instant death from lost momentum.
There actually are two levels of jump, if you lightly tap the button he'll jump a little if you press the button he'll jump a lot. It's really not practical to use at all.
Pretty fun game, those windows are really rather hard.
The music is great, except for the slow part which just makes the mood too dark and makes it easier to get mad. The adrenaline-pumping faster part of the song it spot on for this sort of game though.

Oh i do love auto-fire on the arrows. Us: "Our arrows will blot out the sun!" Them: Then we will fight in the - *FWOOM* *BZAAP* *CRACKLE-BOOM*.
(To auto-fire hold down your desired arrows and then press alt. You'll have to click on the game again to do other stuff, but at least you get to rest your fingers)
Actually big burly units have a way better survival rate since melee units hit ALL the units in front of them at once. So 19 squires would be killed pretty quick by 1 paladin.
If all the waves that are 'all turrets' and the one with 'all turrets with 4 tanks' had half as many turrets, they'd actually fit into their difficulty bracket...
