I played the game today and was able to figure out the code. The game works but it needs some polish. You have some really cool images, especially for the locks and keys but the bottom history area just doesn't match. I was confused a bit at first because nothing indicates how to play so it took some experimentation before I realized what was happening. One thing I struggled with was the hitboxes (for lack of a better term) on the locks. Often I'd try dragging a key to a lock, only to have it drop to the lock below or just not register at all. You can't undo a selection either which can be a bit annoying, but there isn't a limit to the number of guesses you get so it's not like a huge penalty if you drop a key on the wrong lock. The game starts with a screen that says "start game". I'd venture that most players assume you have to click "start game" but that doesn't do anything. The visual indicators are a bit hard to differentiate. It would be helpful to have them be completely different icons rather than just recolored skins of the same icon, especially for colorblind or visually impaired folks. Other than that, The basis of the game is good. It's a fun visual twist on the mastermind game concept. It sounds like you may be planning to have this be a daily puzzle similar to wordle, which could be a lot of fun.

- The UI and background doesn't have enough contrast, it might be helpfull to give bg blury or something darky to be more clearly.

Muy buen juego, la temática de las llaves está super, descubrir cuál es la indicada
