New Prototype Puzzle
About this app
This app is an early game prototype created to explore and test a simple gameplay mechanic.
The experience is intentionally minimal and focused on core interaction and feel. Features, visuals, and progression are limited by design while the concept is being evaluated.
This prototype may receive changes, improvements, or updates based on feedback and testing results.
Thank you for trying it out and helping shape future development.
