+# Day 1
+
+Project initially setup. Followed the video and the book.
+
+I went extra since I already have a perferred setup I've recently grown accoustmed to and I'm going to take advantage of the metaprogramming library I've recently made for myself. Although I doubt it'll see much action...
+
+I'll be keeping the code pretty C like as Casey does in the series. Main purpose is to be able to use whitebox.

+# Day 2
+
+Pretty smooth so far, modular header library is showing its limitations...
+
+I have enough practice messsing with forwards and library linkage now that it wasn't much of a show stopper at least. All the mess is quarantined in the in win32.h and so far it looks like it will be enough to keep it all there.
+
+I added extra stuff in `grime.h`, `macros.h`, and `types.h` that he will either go over soon from my vauge memory last time I just watched him (instead of doing) + stuff from gencpp's version of the zpl library.
