Avia Jet

Avia Jet is a single-player, 2D arcade reaction game designed to test and train hand-eye coordination, focus, and visual attention speed. The app features a clean, minimalistic user interface optimized for mobile devices, focusing entirely on the core interactive elements without unnecessary background noise or complicated navigation.
The main gameplay screen consists of three main components: a central spinning wheel that alternates between actively spinning and completely stopped, a dynamic area where various collectibles appear, and an on-screen score counter that tracks the player's current progress in real time. Users are presented with an interactive text tutorial window called "Rules" that clearly describes all the mechanics, including item collection, point penalties, and win/loss parameters. This instruction screen contains a special confirmation button called "Understood" that allows players to confirm the rules and immediately return to the menu screen.
The basic interactive mechanics require the player to constantly monitor the state of the central wheel and tap the screen rapidly. Items must be selected and collected only during the time that the central wheel is actively moving. Time is calculated automatically by the application. If the player interacts with any element on the screen while the central wheel is stopped, the internal logic registers an error and the player's total score is immediately reduced. This score reduction creates a direct penalty for accidental or continuous tapping on the screen, forcing the user to employ a controlled rhythm-based interaction strategy.
Progression in Avia Jet is organized through a structured system of individual levels. Each independent level introduces certain numerical goals and conditions that must be met in order to progress the level. In order to achieve the win condition and successfully complete the level, the user must accumulate a predetermined number of correct item collections. Conversely, the game has a strict loss condition to maintain difficulty. If the total number of incorrect actions, such as clicking while the wheel is stationary or selecting non-target items, exceeds the number of successful collections, the current game session ends immediately and the player must restart the level.
Difficulty scaling is implemented dynamically across all levels via technical settings for the behavior of the central wheel. As the player progresses to higher levels, the time to collect items becomes shorter. In addition, the time windows between the spinning and stopping phases become more unpredictable. These settings reduce the user's available decision time, increasing the overall reaction requirement and cognitive load.
From a technical point of view, Avia Jet is fully optimized for mobile devices, featuring high touch sensitivity, ensuring that each user touch is instantly registered and processed without performance lag. The application works completely offline, requiring no active internet connection or data transfer to an external server during game sessions. The lightweight code architecture ensures stable frame rates and fast loading on various Android device models, while maintaining low battery and system resource consumption.
