Here is a list of a few games I created in the context of a Unity course I've taken online:
This was the first one, to get introduced with the editor. In term of game, it is a very basic text based game, with a simple branched story and 2 possible ends.
Classic brick breaker game, with a bit of very cheesy story, some sounds and video effects and an epic end.
Galaga clone, with waves of enemies, old school music and 2 bosses.
A hopeless quest
2D side action game with 3 levels, many tough enemies and epic bosses.
