Unity 2D Pixel Art Game Tutorial

Learn how to build a complete 2D Pixel Art Tower Defense game in Unity from scratch! This step-by-step tutorial guides you from a blank project to a fully playable game with a main menu, multiple tower types, enemy waves, and three unique levels.

You’ll learn how to create a modular, data-driven system using Scriptable Objects to manage towers, enemies, and waves, plus how to design forest, lava, and jungle levels with Unity Tilemaps.
