How the super moves work in the Viking game. Taking damage or dealing it fills up your meter (the blue circle around the character icon) until it reaches the top and starts glowing. Tapping it starts up a drawing minigame- if the player traces it accurately enough, they unleash the super move, which is based on the weapon the character has equipped. Although super moves do massive amounts of damage, they aren't a guaranteed finisher nor are they impossible to dodge.
EDIT: Updated interface with more elaborate drawing symbol to look fancier.
Sadly, no... The actual assignment is to design a game document, we don't have enough time in our class to actually create a videogame. I know a lot of people have been asking if it's a real project, so I might try and seek out someone who wants to try making a prototype. Designing concept art has certainly been a blast for me, and designing a whole game would certainly be a real challenge.
