Glitches I have found.

[Blue_Link_34]

So I was playing and testing a few things, I'll show what I found.
Note: I didn't test all that on the web version and I did not look if it was already found by someone on that version. Therefore, I can only guarantee these glitches work on PC.
I took a screen so the explanation below can be clearer: https://i.imgur.com/7rj85Ub.png
I'll explain how I got there and what exactly is happening there.

First step: Get the box through.
When the cursor goes on the arrow, go to the next screen. You might have noticed that you can bring any item in the goat screen. Any item, except one: the box. When you try to bring the box it automatically releases the box.
By dragging the box below the arrow, and being a bit on the right of the arrow, you will move the box a little bit during the screen transition. Now you can see it in the bottom of the screen, and click on it to drag it arround, the ground has no normal colision with the box.
For the other steps, you will need to place the box in the same spot as in the picture. (don't worry, if it is a few pixels off on the left it will slide until it reaches this exact spot)
Note: If you place the box under the waterfall in the ground, clicking it very rapidly with an autoclicker will teleport it on the ground above. At this point put your mouse on the top half of the box and activate the autoclicker. While clicking drag your mouse up, and on the top of the waterfall deactivate the autoclicker. The box is now floating without you doing anything. Actually the cursor still holds the object but it is not displayed. Next time you click the box will drop down from your cursor.

Second step: Time to get bouncy!
This part comes from the position of the box. It can be used as an exploit for the Ready for the circus! achievement!
As you certainly know, if you drop a letter or the cup on top of the box, it will bounce away.
In this particular disposition, if you drop the letters on the right spot like on the image, it will bounce until you move the box. This means that you can make all letters bounce simultaneously.
This results in a heavy screen-shake and loud noise going on that never stops.
You can also make the cup bounce like that, though it is way harder and will take a few tries to get the right pixel. (it will often stay up in the air because of its weird hitbox)
Note: You can fill the cup with water before making it bounce and it won't spill out. More interesting, sometimes when it bounces one time before getting to the part of the ground on the left, it will not spill out. I still do not know why that is.

Third step: Reverse goat and nightmare.
Now you can get the key to the goat's cage. The goat will fall and seems to hit the hitbox of something and get in this position.
I did not test if this was possible in other situations like just keeping the cup below the cage, but it might be worth trying.
And that's it! That's the last action will do. But glitches don't stop now.
You remember when, in second step, I told that the screen-shake and noise never end? That's why I put nightmare in the title of this part. It is really unpleasant to listen to and will still go on after you free the goat.
We can take two conclusions based on that:

1. The game keeps loaded all elements at this point. The rooms, the objects, everything is always loaded.
   
2. The credits take place in the screen right below the one with the goat. How do I know? Because the little white particles emitted from letters bouncing appear on the top of the current screen.Therefore, the credits take place right below the goat room.

That was all I had regarding the picture. But I still have two more glitches to talk about briefly.

• In the breakout screen, drag the cup to the top border of the screen and release it. It will not wall and will be stuck still in the ceiling. You can still get it back just by dragging it down.
  
• If you take the nut in the goat room, you can leave it in the ground because it has kinda the same relation to this room's ground as the box. But the really strange thing is that if you leave it in the blue squares with grey chains, it will start sliding diagonally bottom right. My theory is that these squares are an object from another project with certain properties and the dev copy-pasted it here without removing this property. But I think there is a very small chance of that being the case.

Thanks for reading!
After finding glitches in the preAlpha and Alpha versions of CoinOp Story, I could not possibly avoid trying things in this game.

Also when i got all the achievements steam shows that the game has no achievements but when i click on the game it shows the 100% completion.
