Level 14: “Fall” One doll.
Fire forcefully and a little bit up, a split second after the level begins-- you’ll probably end up catching the goal by accident as the bricks knock into each other.
Level 15: “Fortress” One doll.
Aim high and send a doll into the top left of the “fortress” holding the goal in the upper right corner; with enough momentum, it’ll slide into the goal. I aimed three squares to the left and one up from the “L” in the word “Level.”
Level 16: “!” One doll.
Arc a doll forcefully at the ball, and with enough momentum it will follow the ball through the gap and tumble into the goal. Alternately, for a two doll solution, hit the ball hard with one doll, and the ball should knock the goal onto the bottom floor. Wait for the goal to land, then send a doll horizontally into the goal.
Level 17: “Watcher” One doll.
Aim a few squares above the opening of the small tower, and fire your doll in an attempt to intercept the falling weight-- the weight should knock your doll right in.
Level 18: “One Way” One doll.
Aim a couple of squares below the word “Sound.” Your doll should glide right through.
Level 19: “Fast, Forrest, Fast” One doll.
Aim a few (5?) squares below the words “Fast, Forrest” and arc your doll onto the goal before the stacks of blocks tumble down.
Level 20: “Last… Almost…” Two dolls.
One doll to knock the weight out of the wall, another quickly sent through the gap to catch the goal before the weight knocks it off screen. Watch out for the first doll when firing the second. I fire the first up and to the right of the weight to give it a good shove, but fire the second a little lower and to the left of the gap so that the doll is arcing down once it goes through the gap.
Level 21 (extra): “Welcome to Play4all.net” One doll.
Fire your doll forcefully through the top left brick holding up the left side of the left platform-- your doll should bash through, collapsing the entire device, but slide into the goal before everything falls away.
Level 22 (extra): “Cool site?” One doll.
Aim about 5 squares up from the middle of the upper platform. Your doll should shoot through the gap between the upper platform and the bricks, and slide into the goal.
Level 23 (extra) “Box2d- rulezzzz!” Two dolls.
Aim about 4 squares left, 3 down, from the lone single block. Your doll should bump the rightmost brick under the goal, knocking the goal onto the floor to the right of the cannon. Fire a second doll into it. (Might be possible to ricochet a doll off the single block into the goal?)
Level 24 (extra) “Blind Trust” One doll.
Count 8 lines on the paper from the bottom platform holing the goal stack, and fire right around that line in the line of half-squares at the top of the paper. There’'s some kind of hole in the ceiling allowing you to ricochet off of a hidden wall, enough to send your doll into the goal.
Level 25 (extra) (forgot to catch the name of this, as it jumps immediately to a name entry screen when you solve it) Two dolls.
Fire one doll high by aiming above the a and y in “play4…” above the cannon-- the doll should land on the left side of the brick covering the gap about 1/3 over from your cannon, shoving the brick aside and landing inside the structure of platforms. Arc another doll at the side of the weight at the top of the structure. The ball will be slow but if it begins rolling at all, it will pick up speed from its falls and shove the goal box onto the first doll.
In all 32 points over 25 screens-- I think I was off in claiming I could have achieved 33 so easily before.
