This is a fantastic codebase. The comments are clear and concise, making it easy to understand the original design choices. The code is well-structured and easy to navigate. I've been able to adapt it to my needs without too much trouble, and the core mechanics are solid. It's a great starting point for anyone looking to build upon a classic game design. I highly recommend it for experienced programmers and those learning alike. There were a couple of minor quirks I had to work around, but nothing major. Overall, a very worthwhile purchase.
