One tip: don't use words with a sandhi [1] (like today's word). It makes guessing it many more times harder, since you are actually guessing two (or more) words in addition to the joining letters.
Also, I'd just like to say that this take of Hindi Wordle is the best so far - fill in the व्यंजन (consonants) with the स्वर (vowels) supplied as hints.
Written word-games aren’t a thing in Hindi (like Hangman for eg) but we do have a lot of stuff rhyme based games. Probably other ways to tackle this better.
Interesting observation, and I can't help but wonder if this is loosely correlated to literacy. Since most of these games were developed to pass time by the masses, it only makes sense that they be verbal rather than written.
