IO games are fun for quick bursts of entertainment! I remember spending hours on Agar.io back in the day, trying to become the biggest blob. If you enjoy the competitive, skill-based aspect of those games, you might also like
Geometry Dash. It's a rhythm-based platformer that's super challenging but incredibly rewarding when you finally conquer a level. Give it a try if you're looking for a different kind of quick, addictive gameplay experience. You can find it on Steam, mobile app stores, or their website.
