- **Battle-Tested**: Verified by 2,400+ automated test cases covering virtually all common code patterns.  
- **Hot Reload Ready**: Fully compatible with leading hot-reload solutions like HybridCLR and xLua.  
- **Agile Development**: Rapid bug fixes, prompt feature updates, and immediate support for the latest Unity/Unity Engine changes.  

## Features

- **Symbol Obfuscation**: Supports comprehensive configuration rules and incremental obfuscation for flexible and efficient code protection.
- **Constant Obfuscation**: Obfuscates constants such as `int`, `long`, `float`, `double`, and `string` to prevent reverse engineering.
- **Variable Memory Encryption**: Encrypts variables in memory to enhance runtime security.
- **Function Call Obfuscation**: Scrambles function call structures to increase cracking difficulty.
- **Randomized Encryption VM**: Generates randomized virtual machines to thwart decompilation and cracking tools.
- **Static and Dynamic Decryption**: Combines static and dynamic decryption to resist offline static analysis.
