Kaboom is an effort to make game development more accessible and fun for programmers of all levels by introducing a flexible component system that allows developers to create game objects with various behaviors. The library provides primitives to describe behaviors, such as actions that can be applied to objects, tags that define certain types of objects, and input handlers for handling user interactions. Kaboom also includes helpers for building specific features, like level creation, and an integrated environment on Replit that allows developers to edit, manage, and run their code in a single place, complete with debug tools such as bounding box drawing, hovering inspection, time scaling, and pause functionality.
