Serene Orbs
Read full descriptionHide full description
Serene Orbs is a unique puzzle game where you merge identical bubbles to form larger ones. Each fusion helps you progress through a dreamlike and musical environment. As this is my first game, I would appreciate feedback on the presence and frequency of ads, as well as all other aspects of the application, to ensure they don't disrupt the ambiance. I'm exploring the best monetization model to make the game free and ad-free, relying solely on in-app purchases, and allowing future collaborations with artists for new creations.
