## Description

Novalis is a vertical level‑based mobile game. Its core gameplay involves observing progressive number patterns and responding quickly. At the start, known numbers appear one by one; you must identify the hidden arithmetic relationship within the briefly flashed sequence and select the next correct number from multiple options. Correct answers allow you to advance through higher waves, with the reveal pace gradually increasing. Wrong answers accumulate mistakes, and three mistakes end the round. You can pause, restart, or return to the main menu at any time, and the highest score is saved. The rules are simple yet test observation and reaction speed, making it perfect for challenging extreme win streaks in short sessions.
