Heya all!
Here's today's small patch/improvement update, with a few fixes and small QoL stuff :)
Input: You can use <Shift>+<Letter> to input a <Letter> in a letter slot.
Level 9: A hint now explicitly shows that you can toggle off the "autofill letters" option when you want - typically increased difficulty, or for puzzles like this one where you prefer to input letters in the right position manually ;)
Level 40: Small fix on the computation.
Digit inputs: In special cases (like level 55) where you have numeric inputs (instead of letters), you can now use the keypad too!
Thanks to you all for your continued support and help!
