Very very good, it’s a game changer and if anyone reading this tried it before, I recommend playing again.
Tthe bonus blank works great and yes you made the right decision to allow five letter words with a blank to receive the bonus. 1. It just makes strategising more interesting. And 2. there might not be any five letter word opportunities without using a blank.
And now it’s possible to get close to using all the letters.
That was it, didn’t notice it. Especially as my small laptop screen doesn’t show the lower keyboard row without scrolling. Maybe it’s just me but I think the button could be more ‘enter-y’ looking.
I have two more suggestions. The first one might be beyond what you want to do and completely understandable. If I’m thinking about where and how to use my blanks, I can’t test that a potential word will be accepted until I use the blank. I was going to almost use all the letters on the board but my word wasn’t accepted. So if this is something you think would add to the game you could make it so that the player could type in a word to ‘test’ it.
My second suggestion is as well as showing the total score, there could be a percentage of letters used score. This would be especially useful at the end. For example, even with my failed word mentioned above I used all but three of the letters and I was very happy about this. So it would be nice to have a percentage score to compare to for future games.
PS
In your game description it says:
Scoring is calculated by adding the points of the chosen letters and multiplying them to the number of letters.
It sounds better if the ‘to’ is ‘by’: and multiplying them by the number of letters
