Step 1: Play through all 48 levels perfecting all of them
Step 2: Clean up the miscellaneous achievements
Step 3: Grind the remaining deaths
Achievements unlock only upon going back to the level select screen, which may cause a bunch to pop simultaneously if you play through a lot of levels without quitting.
All in all, this should only take 3 or 4 hours.

Perfection
Training Wheels OffGet a perfect score on every level in Stage 1.
Get a perfect score on Split Second.
Obsessive Compassion DisorderGet a perfect score on every level in the game.
Perfecting a level requires two things:
- Minimal critter deaths
Basically requires you to make no mistakes. Some levels require you to sacrifice a critter or two to hit a button or something, and those won’t count against your perfect rating. - Flinging critters without the aiming line
This can be circumvented entirely by just turning off the aiming line before releasing the critter. What I mean is:- Right click a critter
- Turn on the aiming line (hotkey: a)
- Aim like usual
- Turn off the aiming line (hotkey: a)
- Release right click to fling the critter
With that knowledge in hand perfecting levels isn’t difficult. There was maybe only one level which I had trouble with.
Miscellaneous
Paint The Town RedGet blood on every solid object in a level.
Level 2-2
Fling all six critters into the top saw blade. With enough luck the split halves will spray blood on every wooden block as it bounces around. Getting blood on the smaller square block on the upper right seems to be the rarest.
You can fail the level and still unlock the achievement.
Medium WellSave a Critter that has been char-broiled red.
Level 4-3
Play like you would by and explode the bomb blocks blocking the elevator with an oiled up critter.
Then drag a remaining critter into the flames until it’s fairly red (just before it ignites) and fling it into the elevator.
Insta-SkillHave every Critter (at least two) in the level die within a one second timespan.
Level 4-3
Send the oil drum left to where your critters are and ignite the oil drum with the nearby flames.
Level 4-4
Press the blue button by igniting the top row of barrels, but let all your critters fall to their death simultaneously.
Conflagration SensationGet 40 fires going simultaneously.
Level 4-4
I’m unsure if the flames on top alone are enough for the achievement, but you can just spread some oil along the left wall as well for more fires.
You can fail the level and still unlock the achievement.
Viva VarietyKill Critters by all available methods: falling, spikes, buzzsaws, explosions, fire, and electricity.
5-2 is the first level with electricity – the last of the 5 obstacles.
Low FlyerBeat Hang Time without the Critter leaving the screen.
Level 5-3
Easy one. Just don’t launch the critter too high when hitting it with the spring.
IngenuityFind two different ways to set off the Oil Drum in Despair Mail.
Level 5-7 (source)
So you have to find 2 different ways:
1.) Let the oil drum float to the left inside a bubble. When it is in the right spot press the laser button by throwing the bubble-maker at it.
2.) Let the bubble-maker float to the top to the laser button (inside a bubble). Shortly before it hits the button throw the oil drum to the left in the right timing, so that it is set off in the right spot
I Demand A RecountSave more than three Critters in Six Enter – Three Leave.
Level 6-5 (source)
… In that level you need to save 3 Critters for perfect and 4 for the last achievement. I made it with throwing the first 2 Critters directly in the first 2 holes & then let 2 fly with a bubble to the last hole + busting the bubble with the remaining Critters.
Everyone Hates This OneSave all Critters in Gone With The Wind in 45 seconds.
Level 6-6
Not much to explain, this one is all about going quick. What I did was:
- critter #1 onto the red button
- critter #2 onto the yellow button
- save critter #1 by flinging it right
- save critter #2 by dragging it right (make sure critter #3 and #4 don’t fall to the lower step)
- send critter #1, #3, and #4 into the elevator
- save critter #2 by flinging it right and send it into the elevator
Restarts + Deaths
Failed At Life, Okay At DeathReach 30 lifetime level restarts.
Die CentennialGet 100 lifetime Critter kills.
Decline InterventionGet 250 lifetime Critter kills.
500 Slays of BummerGet 500 lifetime Critter kills.
Self explanatory.
6-7 is by far the quickest for grinding deaths. The level has 9 critters that all start very close to a rotating saw blade.
