This game is fun but can pull resources from low-end machines. The encryption is a negative effect on performance.
To conceal data it's best to build it directly into the coding. The decrypt/unpacking slows down the game.
This game doesn't use any encryption. The game generates levels on the fly, that may be what you're referring to. Thanks for the feedback!
For some reason when I ran the game the process was purple, which indicates the file being packed or encrypted. Unless it's setting off some sort of security false alarms.
