Tolle App, aber

Ich liebe diese App, allerdings scheitere ich regelmäßig an der X-Wing Strategie. Ich fände die App perfekt, wenn diese einem anhand dem aktuellen Rätsel erklärt wird und nicht anhand irgendeines leichteren Beispiels.

💜 Challenging & fun

I love this game and the other games from this developer. That being said, this is my favorite because there is always logic behind every decision and there’s a sense of gratification whenever you complete a puzzle (even the easy ones!).

Gute App, aber

Ich habe das Spiel echte gerne gespielt, bis zu einem gewissen Grad war dies auch möglich. Aber jetzt geht es quasi garnicht mehr ohne irgendeine Abo-Andreherei. Schade.

Response from developer

Hey Jeff, schade dass dir Guriddo keinen Spaß mehr macht. Was genau meinst du mit "Abo-Andreherei"? Am Bezahlmodell der App hat sich seit Jahren nichts verändert :/

I don’t understand it…

I read the tutorial several times and I still don’t understand how the game works.
I think that the tutorial should be reworked.
I’m surprised that a company like Simon & Schuster would put their name on a product that has so many grammatical errors.

Response from developer

Oh nooo, the tutorial should enlighten, not baffle! 😅 Guriddo is actually a solo project—just me, my laptop, and too much coffee. No Simon & Schuster behind the curtain. I’m sorry the tutorial didn’t click for you—maybe you can give me as a non-native speaker some feedback where you saw grammatical errors. Thanks for the honest feedback! ❤️✌️
