Devichi was an adventure side-scrolling game that I worked on after my high school graduation.
You play as a little monster named Devichi, granted the ability to stop time itself, in order to save your family. However, It is now discontinued because I got a little too ambitious with the features, so doing the art, gameplay, music, and design was too time constraining.
Devichi has a very basic battle system. You can move around, and attack, that's it!
The mechanic that makes the game special is the ability to rewind time. At any point in the game, you can rewind time to an earlier state to fix any of your mistakes.
There was also a compelling story in the game, though, I have never finished writing it.
