Is there any cheats i could use? Like creative mode?

This may be necroing, but yes and no. If you were to find some way to edit the IndexedDB, you *could* change your savedata. I tried and failed, but maybe someone smarter could give this a shot and tell us what we need to do!

the easiest way of cheating is though cheat engine, but that doesn't aways works, didn't test on  this game

Apparently it's possible on the newer version with the right extensions. It takes an extension to edit the IndexedDB(I used an Chromium/Firefox extension called Kahuna), but you can simply export it, edit it, and add it back. Not sure if this works on Iconology, but did it on the Numbers update without issue. There may be lag on the order of 2 seconds per move, but that might just be from playtime.
