Hi Rosa,
Thanks for your comments!
There are buttons to go back to the menu for every scene, not sure why is not showing in your computer, maybe try full screen?
And for other scenes, the users need to find out the hidden button from the scene and the secret message will pop up, I did mention these in the pop up message and comment section but like you said, the text style is little bit hard to read. I quite like the style of the font though (it matchs with my Minecraft objects) and it is good to know the users may not find it the same way.
Thank you for your comment again and I will do it better next time😊
Cheers
Rosanna
