KIKA is a 2D mobile game I built end-to-end in Unity. There was no team and no division of labor — I made everything: the art and sprites, the sound, the menu flow, every level, and all the C# behind it.
Doing the whole thing alone is the part I keep. You can’t hide a weak idea behind someone else’s polish, and you feel every tradeoff directly — a level that’s clever on paper but miserable to play, a menu that’s one tap too deep, a jump that’s a few milliseconds off and suddenly feels wrong. KIKA is where I learned that game feel is real, unquantifiable work, and that shipping something small and whole beats designing something big and theoretical.
