SPOILER WARNING
Here are the steps to Hapland 2 if it's driving you insane (I think I wrote them correctly):
PHASE 1: General crap
1. Turn on the lamp in the upper left corner and shine it on the cannonballs.
2. Click the bird, and as it carries a ball past the first cloud, click the cloud to make the bird drop the ball, destroying the electrical pylons below.
3. Repeat above, only at the second cloud, in order to drop the ball on the catapult.
4. Click the red sign on the platform to change it to a green arrow.
5. Open the trapdoor to the right of the sign.
6. Click the arrow below the sign to light it up, making the man there walk in that direction and fall through the trap door.
PHASE 2: Setup
1. Change the sign back to the red circle.
2. Click the box with the pink lid to make a bomb pop out.
3. The man will toss the bomb in the air. As he does, click the yellow arrow under the red sign. A charge will shoot out and knock the bomb toward the building.
4. Quickly click the rod that the arrow sign attached to the building is hanging on. The arrow will spin around, saving it from being blown up when the bomb hits.
5. Click the pink lid a few times to make a ramp.
6. Turn the arrow so it faces the building.
7. Click the man so he walks up the ramp and into the building.
PHASE 3: Clearing the way
1. Click the two upper electrical switches underground so they're both yellow and activate the staircase.
2. Click the left arrow on the small wheel underground, and then the staircase to roll it to the right.
3. Click the arrow to it once again faces left.
4. Ring the doorbell. The man walks out and follows the arrow up the stairs to the catapault.
5. Click the left-hand cloud. The next time you click it, it will blow up, leaving a flaming mess behind for a second or so.
6. Quickly click the man at the catapult to fire the cannonball. It will fly through the flames and burn through the curtain at the castle, taking the land mine with it.
7. Turn the arrow to the right again and click the man to have him re-enter the house.
PHASE 4: The first torch
1. Click the man farthest up in the castle. He will jump off the top ledge and land below.
2. Click the coffin in the upper left of the castle. A man jumps out, chased by a fly.
3. When the man jumps down, spin the air vent to suck the fly through.
4. While the man at the lever is being harassed by the fly, click the other man to have him run below the box.
5. When the fly leaves, have the man there pull the lever to drop the box. A fish comes out.
6. Click the leftmost guy to get him to the bottom castle lever. Make sure the arrow below is pointing right, then pull that lever to start the current.
7. Have the man standing on the middle ledge pull the lever to open the trap door and the fish falls through.
8. Click the gate to open it and the fish will hook itself on the fisherman's line.
9. Stop the current.
10. Click the fisherman. He'll walk out on the pole to get the fish and be flung to the top of the castle. Click him once more to get him in the door and light the first torch.
PHASE 5: The second torch
1. Start the current flowing right again.
2. Make sure the arrow attached to the house is facing left.
3. Click the window. The man inside slams it shut, making the blob fall off the building.
4. Click the blob. It goes left, eats the bomb box, slides into the water and is swept right by the current straight into the land mind, blowing both of them up.
5. Stop the current.
6. Click the underground wheel's left arrow and roll the staircase left.
7. Ring the doorbell, the man walks out.
8. As he passes over the second box, click it to make him get pulled inside.
9. A vehicle will roll out, into the water.
10. Click the gate to allow the vehicle through. The man gets flung out, going in the other door, lighting the second torch and completing the puzzle.
