First of all, if you haven't yet played
Paper Moon, go do it! Seriously!
For those of us who are completionists, I'd like to put together a guide that will help players find what they need to get all the achievements, specifically: checkpoints (so you can die at them all for the Paper Lemming achievement), cherries (to help get the Cherry Pie achievement), and Time Bonuses (for the Flux Capacitor achievement).
The list below may not be complete for two reasons: 1) I haven't yet gotten the Paper Lemming achievement, so I may not have all the checkpoints (or I do but I haven't died at all of them yet); 2) I may not have written down everything I found, since I didn't start writing them down until later. Feel free to collaborate and post anything you find that's not listed. It would also be cool to share tips and tricks, etc.
Anyway, here's what I've got:
CheckpointsLanding- In the starting boat
- At the dead fish, just before three rocks in the water
- Just after the three rocks in the water
- After jumping up the planks to a palm tree, just before the switch
- At a platform reached by pushing a rolling barrel, just after the well
Lower Caverns- At the bottom of the initial drop
- Just to the right of the initial drop
- After a couple of jumps to the right of the initial drop, before a poppable wall
- Past the drop after a group of three bats
- Just after passing a crab and jumping over a stack of stationary barrels
- Just after passing two oil drops and a couple of bats
Upper Caverns- Shortly after the start point
- After ascending a series of planks, next to a rolling barrel
- At the very top of the cavern, after ascending a second series of planks and pushing a rolling barrel
- Just under and to the left of the giant doors
- Left of a pile of three rolling barrels, near some bats
- Along the side of the cliff after the pile of three rolling barrels
- To the left of the giant pile of skeletons
- To the right of the giant pile of skeletons
Clock Tower- Starting point
- Upon entering the clock tower
- At the top of the gears and bats section
- Just before the switchbacks with the descending crony
- At the switch at the top of the switchbacks
- At the wall of gears right after the switchbacks
- Near the top of the clock tower, on a platform below the movable platform
- At the top of the clock tower, next to the skeleton sign
CherriesLower Caverns- In an alcove along the right side of the initial drop
Boat Bonus- In the last jump before the lighthouse
Clock Tower- Left platform above the gears and bats section
- Just above the gears and bats section, where you first encounter a crony (must jump to death)
- At the switch directly below the skeleton sign, past the movable platform
- At the final exit
End Credits- When Matthew Wegner's name appears
Time BonusesLanding- To the left of the starting boat, in the water
- Down the well
- Just past the well, behind the rolling barrel
- In the giant jaws leading to the Upper Caverns, under the "Star Steps"
- At the boat leading to the Boat Bonus level
Lower Caverns- At far right exit, past a pit containing multiple crabs
Upper Caverns- At the very top of the cavern, after ascending a second series of planks and pushing a rolling barrel
- In a hidden alcove at the bottom of the cliff with three rolling barrels at the top
- In the bottomless pit exit, just after the cliff
- Under the pile of skeletons
- At far right exit, just past the "Death is no obstacle" puzzle
Clock Tower- Left platform above the gears and bats section
- Next to the switch directly below the skeleton sign, past the movable platform
Tips and TricksShave off a few seconds at the end of the clock tower. When you reach the wall of poppable gears, jump up the left side of them. Then jump and immediately pop them out. Aim for the top of the wall of gears, and pop them again to land on top of them. This saves you from having to jump across the bottom row of gears, climb up, then go back under the dripping oil to get to the same place.
