This is a class project I made in 2013 using only the graphing tool of Turbo C. It's a labyrinth game that uses elements such as switches and doors to add a twist to the difficulty, which makes it a true puzzle game. I created my sprites based on retro-games you might identify.
To execute the game launch 'labyrint.bat' from the root folder, DOSBOX will take care of things.
I have included my 'source file', and it is quite messy! But it worked for me. :)
