I think we made nearly the same game :)
I like your mingame for sharpening/grinding. It is cool with the "WASEDE...." characters.
I see it so often that people don`t put sounds in their games, but it is sooooo much better, if there is any sound and music, there is so much good free stuff on itch.io for example which you could put into your games.
And if you include arrow keys for movement, you should also always include WASD (that is the standard nowadays)
