My goal with Gun Runner was to create a First Person Shooter that was on-rails and also featured some of the specific tropes of the Endless Runner Genre (replaying levels over and over, improving attributes each time so you make it further along, difficulty ramping up as you progress). I've decided to make it so you spent money to be allowed to 'run' for one of four factions and you have a different loyalty level with each faction, allowing you to buy different levels of boosts.
My goal with Brooman Potionmeister was to continue in the vein of procedurally generated maps and add some roguelike elements to it. I also wanted to create a crafting system which worked a bit like a puzzle. There was also an inventory and an actionbar where you could place potions and items to use them.
My goal with Jesterquest 3D was to remake an old game from a dead system called 'Videoway' using 3D graphics. The controls are still 2D, but the maps are more or less made out of 3D elements and primitives. I wanted to remake the game while adding some power-ups that weren't present in the original.
My goal with GridDrill was to learn how to use basic Unity functions such as drawing things on-screen, using UI elements such as Buttons and ScrollViews and things like that. Everything in this game is very simple, there are no complex animations and the music was taken from existing games.
