I think it's a good game. I'm proberbly not the target for this kind of game, since I'm not very good at word games.
I found this game a little too hard, but other players might find the difficulty to be good. Wordle wasn't my kind of game either. Maybe highlighting vowels could make it slightly easier for dumdums like myself, but I have no idea if that would make an effect.
The UI feels refined and even the web version on mobile has a native feel. If it didn't have a share button to compare the daily challenges with friends thrugh pasting in groupchats, I think you should add that (I couldn't solve the daily challenge, thats why I don't know if it's implemented)
I didn't even know the dash was optional. I guess you learn something new everyday.
