I'm not sure what the purpose of this application is, but it's indeed a text editor.

This text editor is amazing and helped me get through a really hard time at school. Thanks so much for making typing so fun! (Also, I love how the various Itch.io descriptions call this text editor a "thingy" like "You own this thingy"  or "Rate this thingy." I keep reading these in an overly serious tone of voice and then getting amused)
