Tetris II
This is the second part of the Tetris challenge series. In this version, the user interface, game loop, and React components are already implemented for you. Your goal is to focus purely on the game logic by completing the utility functions in src/utils.ts. You will implement piece generation, movement, collision detection, and row clearing to make the game functional.
Reflex Click Game
Build a simple reflex game where a colored circle switches between red and green. The player must click the circle only when it is green to score points, while clicking it when red ends the game. The game also includes a countdown timer and a score counter, and the player wins if they reach the target score before time runs out.
