The creatively named 'Adventure' is an unfinished adventure game inspired by Legend of Zelda and Final Fantasy. Our CS teacher would not accept games that had violence, so our characters 'attack' with pillows and massages. The map and the character sprites are from past Zelda games, but can easily be switched out.
This was my final foray into 2D games during high school. It's written entirely in Java using only the standard libraries, no special game or graphics libraries. I also had finally figured out how to smooth frame-rates so it doesn't run differently on different machines (a big achievement at the time :P).

I am currently working on a programming language called Elm, and used it to start on making a similar game. The code is a lot shorter in the new version :) http://elm-lang.org/edit/examples/Intermediate/Walk.elm
