The code isn't perfectly organized (eg. the file containing the main loop is literally called "foo.py"), but it was still clear enough to convince me that implementing 2D skeletal animation from scratch was actually a reasonable task for a hobby game, something that I ended up doing myself.
I didn't even feel like it had much of a focus on gun fights, but apparently it's like a detailed firearms museum. They also have airsoft product placements... I'm not that surprised, some people probably bought the featured airsoft guns purely for display.
Interesting, I would have made the opposite assumption ("the satellite is moving so much faster than everything else, we can estimate the interval from the satellite's speed alone). It seems both speeds might have a similar impact, as per sibling comment.
Love my infrared thermometer for steeping tea at exact temperatures. These things are terrible for medical purposes since they only measure surface temperature, but they're perfect for diagnosing industrial machinery and tea. Also more versatile than those expensive programmable tea-brewing contraptions!
And yes, a more efficient browser version is possible (and possibly simpler). People like to fixate on platforms, but it's all about implementation.
