Title

Review- great app to gain resilience and learn with confidence!!!!!!!!!!!!!!!

Nice game!

This game is really fun. I like it but I am getting confused a lot, for example it says k2 means 3 letters up, and k1 means 2 letters up, but when I try that and am playing in k1 then reveal the current letter, it is like 6 more than should be, and when I reveal the letter next to it, its either more or less than before, which is very confusing. Still, I love the game! keep it up!!

Response from developer

Hi thanks for playing the game and the feedback! k2 doesn't mean 3 letters and k1 doesn't mean 2 letters up. It's just in that example in the tutorial the keywords are located that way, but in real games they can be located at any place, which makes the encryption harder to guess.

A good start - GUI needs improvement

Functionally, the game is fine. It allows for what it promises, and if you like ciphers, you're likely to enjoy it.

The negatives are in the UI - text is so small on my MacBook Pro that even with my glasses I had trouble reading it, and there's no option to make it larger. The font selector is available, but does nothing.

I would like to see the gameplay offer more options, like 'clear all but revealed,' and perhaps show revealed letters in a different color, to know that they're 'known.'

A fine first effort of a game.

Response from developer

Thanks for the feedback. Now the font is larger on MacBook. I'll add the feature to mark revealed letters differently later.
