Open Sourcerer
SteamOpen Sourcerer is a 2D platformer where you use JavaScript to control and customize your spells. You will learn the basics of programming in JS in a safe, sandboxed environment with a mix of traditional APIs and custom spell dependencies - the building blocks of your offensive and defensive abilities. Solve puzzles, defeat enemies, and build your own abilities in a story-rich platforming environment. No prior programming experience is necessary.
Need to cast a fireball? Require the "fire" dependency in your code and instantiate a Fireball instance. Everything from magical attacks to character movement can be controlled through code, allowing for expressive play styles that allow you to front-load the complexity of combat into scripting.
The core game loop is learn -> experiment -> explore. In the learning phase, you'll complete coding challenges to unlock new abilities. In the experimentation phase, you'll tweak these abilities through constructor args, callbacks, and control structures, and in the exploration phase you'll test your newfound abilities against challenging waves of enemies as you progress across levels.
Will this game teach you to be a professional software engineer? Nope! That's not what this is for. This helps you answer a more basic question: "Do I enjoy programming?"
