One Click Lemonade is a small incremental clicker microgame built in Omma by Spline, where players harvest lemons from a handcrafted paper tree, fill a pitcher with lemonade, and sell each cup for one click while gradually growing their tiny lemonade empire. The project is designed as a calm, tactile interactive diorama rather than a large simulation, focusing on a simple resource loop polished with playful progression, clear interaction, and a strong visual identity. Its style combines a monochrome papercraft world, soft paper textures, sculptural white forms, and bright yellow lemons as the main accent, making the whole experience feel like a handcrafted interactive object that is quick to understand, visually memorable, and enjoyable in a short session.
