hello everyone! This mod is my first dos mod. This mod is modified on the basis of all the rooms in the original version. The room connection remains unchanged and the process has been modified. You need to use bugs and skills to defeat this mod! It's still a little difficult. Now I only do level 1, 2, and 3! I will continue to update other levels. I hope you like this mod
