The game seems abandoned by the developer and it's a shame, because I found it very pleasant and it would deserve more attention.
Emerge that natively has two achievements problems.
Scrolling through the discussions we find an old "promise of a sailor" of rapid solution.
Instead, the community had to provide alone.
Thank to codecab for its contribution.

Patch with fix is available on:
https://letraduzionidirulesless.wordpress.com/love-is-dead/

To get "Pancakes Forever" now are are sufficient 211 packakes.
For "Exotic Snacks", however, the code was totally incorrect; so I had just buffered the problem, until codecab provided the complete accurate code for solution. So you can obtain achievement no more than satisfying his request.

Download the file (it is the second, with the pets icon), launch the executable and follow the guided procedure, selecting the game folder, if it is not in the default path and launch the game.

If you have never played or haven't completed the game, play normally: now everything is fine!

NOTE: The patch applies to the currently bugged version v1.1.1.0 of the game (wich will become 1.1.1.1)
An update is now unlikely. We hope anyway!

So you will achieve "Pancakes Forever" just playing any level (last course is only reunite with pets) and "Exotic Snacks" completing the quest.

I loved this game, but it is shameful to sell software in this state for 12 $/€/£ (in sale spring 2020 first time at 2,99!), forgetting of it, without providing any post-launch support.
