MageMaze is an indie mobile game that I worked on for about 4 years with Kristof Minnaert. (We both ended up being too busy working on AAA games as our day jobs to finish the side project.)
MageMaze is a puzzle-based dungeon-crawler where you not only explore the dungeons but also get to rearrange the environment by sliding rows and columns of tiles to block monsters and allow yourself access to treasures and weapons. You play Sviking warrior Svenn the Svalliant. You wander the dungeons of the evil Yngvarr the Ynvoker in search of gold, treasures, and weapons with which to slay the creatures therein.
While Kristof and I co-designed the title, I created all things visual in the game: Character sprites and animation, effects, environments, all UI, and all Marketing artwork.
