Can someone help?

I'm pretty new to this, and I need some help with making a level select screen, and a transition into the level select screen from the title screen. Like a button or such.

The easiest method is to use a text-based menu controlled by the keyboard, but clickable GUI is more user-friendly. Text-based menus are pretty easy to code, and there are a few GUI libraries on MicroStudio.
