To be honest, this game quite fun to watch and relaxing time, but the achivement is kinda madness for me, at first i kinda hopeless and about to uninstall it immediately since all i can do is drag, shake, rotate, play musical note, watch sunrise and the scripted words for mountain "Thought".

i see the bomb achievement "Ouch!" and "At least I know I'm alive." and i was wondering, why i never get or even see any bomb objects? so i decide to unlock all achievements except the bomb "Ouch!" and "At least I know I'm alive."
This guide made based on my experience to get 5 bomb just in 2 days (not full time of running this game tho)
It's working for my friend too btw, so i decide to share this tips for you guys who might still stuck with the bomb achievements.

[1] don't get annihilated while doing this tips
• if you get annihilated while doing this tips, please close your game instead click "retry", then start the game again and it will starting from your last save point so your progress still continue
[2] don't shake the mountain
• i don't know this one will affect much or not, but i never shake my mountain while doing this guide only rotate it sometimes for drag some objects
[3] turn on the artefact option
• make sure the artefact option is on, since the game will disable the artefact option every time you start the game (the artefact code : vmvmamamadadadgnanad )

After you turn on the artefacts option, you might need to let your game running background and doing other stuff while waiting the objects hit your mountain (except you would like to sit and watch few hours of your mountain) and wait until quite full of them then go to check for the bomb (i personally leave it for 1 or 2 hours then go back check to find it there any bomb). You may also turn off the sound to avoid the buzzing sound when the mountain watch from outspace.

you must clean your messy mountain if not yet found any bomb but never throw away the objects that hit the mountain, when it's full like this


i just drag it to below of mountain, just like this

you can stack the object incase you don't know, so the object can be drag all together to below of mountain, like this


the obejcts may stick together, but remember that only the most bottom of object can be drag along with other obejcts that stick to it (usually i put larger object size as the bottom so i can easly drag it out)

when i see my first bomb, i so happy and thought it might just luck, then i repeat what iam doing, not long like after 2 hours after letting my game running in the background, go check the messy mountain, i found my 2nd bomb! so i detonate it immediately without thought to write for this guide before. After realize this trick making easier for get the bomb so i repeat it and viola! i got my 3rd bomb after spend next 2 hours or less, so i screenshot it and this is how the bomb looks like (i clean my messy mountain before take the screenshot so it more visible)


i also notice the size quite big, i think it's have the status like other objects that may hit in larger or smaller size, now detonate time! (just click the bomb)


You might want to note that, after the 3rd bomb there is possibility the apocalypse may coming to your mountain, because i face the apocalypse after the 3rd bomb and i thought it might just some random apocalypse, i close my game instead click retry and let it like 1 hour, checking back it's get annihilated again, so i was sure this is not some coincidence, i close my game and turn on the game Sound so i can know when the apocalypse coming, after survive from being annihilated, there is no more apocalypse coming.

when i was so sure about this, the next day i repeat this and it's take a bit longer for me to get the 4th bomb so please be patient. and so i spot my 4th bomb after long waiting from 2 hours, drag to below of mountain, let it run 2 hours more and so on then i spot my bomb which come in more smaller size then previous bomb , can you spot it ?

it was right there




i like to drag all mess to below of mountain before detonate it


and here i thought need to spend another few hours to get my 5th bomb or last bomb for unlock the "At least I know I'm alive." achievement, then while dragging the objects, spot some ball like the bomb but not have the fuse at the corner of mountain betweem surface and below of mountain, so i want to quick drag and drop it to below of mountain and suddenly it's explode when i click on it and quickly screenshot it


it's seem the bomb fuse facing to surface so i can't see the fuse and accidently detonate it since bomb cannot be drag like other objects that hit the mountain, this mean you can have plenty of bomb stick to your mountain at the same time, at first i thought that you can have only 1 bomb and must detonate it first so another bomb can coming.

And so the end of this guide for get the bomb based on my experience, i no longer need the bomb after spend a lot of time for this "unsure" bomb incoming and it's took a lot of effort to get it. for other achievement you can found it from other available guides.
Iam sorry for my bad english (if there any, since it's not my primary language).
thank's for your time to reading this guide. hopefully this guide help and goodluck!
