Question about the game Dimhaven and it’s difficultly.

I’m a very casual puzzle game enjoyer. Games like portal and Supraland

I played the Dimhaven demo and really enjoyed it, up until the last puzzle - the Visa number one.

While I can appreciate it, and all the power to people that like harder more in depth, critical thinking puzzles like this, they are just not for me.

My question is, how is the rest of the game difficulty wise? If I had a lot of trouble with that puzzle (I understood what I had to do, but in the end I just couldn’t figure it out and had to google), should I just skip this game?

Any help is appreciated
