[Suggestion] Level selecting/entering screens need help text

It was very unintuitive for me when I've entered the world for the first time. I guess some people may stuck at those screens too. So it would be very helpful if the screens had some help messages with explanation like:

• "Use arrows to select the level. Press Enter to start the level"
• "Press Enter to start the game"

Suggestions

• Start game - Story mode - Select the level -> there should be some kind of the text
• Select the level - Enter the black screen -> there should be some kind of the text

SuperTux made it 20+ years in development without this being an issue, it's really not everybody who has this issue. However, considering the Steam and Google Play releases, it is to be expected that people with the least amount of experience with gaming in general will discover SuperTux (which, IMO, is a good thing, but will indeed require adaptation). I'm not sure if SuperTux should give instructions all the time like NSMBW, but perhaps a tutorial of some sort when the game is first launched, a bit à la STK, could be interesting.
