Whether you purchased the game long ago or got it free, this guide should speed up any missing achievements you need to grind. These are the methods I used and found the most efficient.

The goal here is to collect 3000 mini TVs and 300 big TVs across all levels.

I did this by achieving perfect status on all levels up to Chapter 4, Level 1.
You cannot obtain 50 mini TVs and repeat the level for 50 more.
Completing all levels in Chapters 1, 2, and 3 to perfect is exactly 3000 mini TVs and 300 big TVs.

The goal here is to retry or die 30 times on one level in a row.

If you somehow don't have these achievements... You're a god or goddess.
Pause the game and keep clicking 'Retry' (or keep dying).
This has to be done in succession. Finishing the level on 29 deaths puts you back on 0.

The goal here is to grab 400 lianas across any number of playthroughs.

Go to Chapter 3, Level 1.
Jump onto the liana at the beginning over and over again.
You don't have to touch the floor. Just change direction in mid air. It does count.

The goal here is to use 600 circuits across any number of playthroughs.

Head to Chapter 3, Level 3 for these three.
Fire across the three cannons and enter the circuit on the left.
Once out, run across into the pipe on your right, and head left back to the start.

The goal here is to slide on 500 bars across any number of playthroughs.

I used Chapter 3, Level 12 to boost my remaining slides.
If you don't want to wait for the achievement, this is the fastest place.
You don't have to slide on the bar, just jump on it.

The goal here is to use 600 cannons across any number of playthroughs.

Chapter 3, Level 16 is fantastic to boost cannon usage.
Every 7.50-8.50 seconds (including respawn time), you will use 8 cannons.

The goal here is to dodge 1200 boss attacks across any number of playthroughs.

If you don't have this achievement by the end of perfecting the first three chapters, I recommend Chapter 3, Level 17. Each dodge will take roughly 8.80-9.80 seconds.
Remember to jump the bosses lazer beam when waiting (or jump high before crossing).

The goal here is to accumulate 1000 Deaths across any number of playthroughs.

I strongly recommend using Chapter 4, Level 1.
Every death on this level, including respawn, takes roughly 2.60-3.20 seconds.
Hold right arrow (or right analog stick) and die over and over.



*Bonus tip: Leave your finger pressed on the right analog, go in Steam Overlay and browse the web. Your character will continue to kill himself in the background until you let go.

The goal here is to jump 5000 times across any number of playthroughs.

You should have finished this pretty quickly. Do not aim for this achievement.
If you somehow end up needing this last, pick any level and jump on the spot.

The goal here is to play for 4 hours across any number of playthroughs.

Chase all the other achievements first and forget about these.
If you have all the others done, just leave the game open (unpaused, in a level) to finish these three.

I hope my guide helped you obtain all achievements on Mechanic Escape.
If it did, leave a rating so others can find the guide easily please.
