Super polished! Wow!
The font is not that good to read.
I don't know if it was a bug or not, but the colors of the password challenge changed between one attempt and another.
Maybe I'm bad at it, but I found it very complicated. I almost don't get past the tutorial :( Between having to read the instructions with the time decreasing, the colors changing between attempts and me having to remember what the results of the previous attempts were (with my terrible memory), I needed to try six times to complete the tutorial and I couldn't complete the next level. Even setting the time to infinite, the password kept resetting without me being able to guess the correct one.
The game is SUPER polished, very beautiful and the SFXs are great (I would just make the clock tick a little quieter than the other sounds), but I believe an adjustment in difficulty would help a lot. Maybe a history of the last attempts, maybe instead of having a limit on attempts, after a certain amount, each error decreases a few seconds off the time.
Anyway, congrats on getting so much done in just nine days! :D
