How to choose Game Development skills

Pick the skill for your engine first, then the system you are building, such as movement, physics, save data or UI. Because a single pack dominates this page, compare its approach with the few independent skills before committing.

  • Prototype a playable game loop in Godot or Phaser
  • Add pathfinding or behavior trees to enemies
  • Package and publish a build to itch.io
