Thank you so much for this detailed feedback.
Level 17 is a good example of how people think differently. Some find it easy, while others find it hard. That's all the difficulty of game design in puzzle games.
I’ll be more careful with my spelling/grammar next time. I just wrote the text as I was thinking and didn’t really review it. Thanks for noticing that.
And about the font, I totally agree with you, I like this font but it's not the best one for reading. I thought about that while making the game and with all the things to do I forgot ahah.
Thanks again for the kind words !
