You should put backgrounds behind the textbuttons. In my opinion, Plain white text looks very dull in UI.
Also, I think the ‘Other’ textbutton should be placed on the far right (Right side of the ‘Progress’ TextButton).
Other than that, the Menu looks very good, especially the forest backdrop. Great work!
It’s a decent design I feel like the options placed onto the home screen looks quite interesting but simplistic. However, a few things you could do to improve your design to look more eye catching.

You could even add a transparent gray image so when players navigate to the UI it’ll be something behind the text;
(For gathering small ideas) I would try using UI from games to get an overall approach on how you’re wanting yours to look like.
Few examples of UI styles and ideas to take along designing yours.
