💡 game.tips

- Take your time to understand the game's core mechanic before rushing. - Explore every corner of each level — hidden bonuses are often out of plain sight. - Retry difficult sections with a focus on one improvement at a time. - Check the pause menu or settings for difficulty options if the game feels too hard.
