If you crack open the EXE (7zip will do it), you'll see a "src" folder within, that's where all the engine logic lives (in the deployed version). So it's within the EXE but you can open it with any zip archiver thing. I see the issues you're mentioning as well, and I'll get them fixed for the next release. Let me know if you find anything else, it's "whack a mole" for real!
