Congrats on releasing this. Having played through and reached the target word, my suggestion would be to try to find a way to lower the difficulty for new players. With Wordle as a new player you can just type in words make some progress and then work out more advanced strategies later on. With Spindle for me it felt frustratingly hard and not much fun at times I'm afraid.

After checking back here a few times I eventually got that I could only spin valid words but they were hard to find so I ended up relying heavily on 2 letter words to reach my final score of 35. Assuming that you support valid Scrabble 2 letter words https://scrabblewordfinder.org/two-letter-scrabble-words you end up spinning words that sound like gibberish most of the time so it seems a bit arbitrary when you can't spin titles like Mr or Ms. :P. Perhaps allow a few free spins to help people unblock the board? Or allow people to skip past problem letters every now and then so that they can spin longer words?

All the best with further development!
