Just bought Handmade Hero today. I can build and run the game now. I haven't watched all the episodes yet (I only watch specific episodes when need to) and just wanted to try out the current version of the game. There isn't seem to be any guides for me (like key bindings, how to enter debug mode, cutscenes, current features and how to use them, etc). I also want to try out some other side projects like Handmade Ray (haven't watched any episodes). But when I tried to execute the ray.exe, it said "Unable to open MERL binary". There isn't any readme.txt for these side projects so I tried to build it the same way as HH (from the w:\handmade) and it was built successfully (until I failed to run it :<). Can someone help me with how to use HH and other projects? I don't know if there is any written guide.
