- Just what do the various points on the neural net represent? At the moment, without the source/more documentation, users can see that something is going on, but not what.

- It's sometimes hard to click on a critter without pausing the simulation.

One bug: the suggested save file names - eg 'NeuraQuarium Save 03/06/2021 13:01:49' - are not legal in Windows because of the / and : characters.

I'd rather not be running this in a Windows VM in the first place. It's using  Mono and Unity, isn't it? Is there any chance of a native Linux version?

Hey, thanks for the feedback!

I'll do the quick answers first:

• I've had trouble clicking on critters too, especially as they evolve to be smaller and faster! I went ahead and added a hacky little solution -- if you click and it's a total miss (nothing under your mouse) the program will do another search with a wider radius.
• I can't believe I missed that issue with the file name suggestions! Fixed that.
• I never considered a Linux build, because (a) I didn't think there'd be much demand and (b) I don't have a Linux machine to test on. But why not? There's a Linux build available now in the downloads. Let me know how it works for you!

Finally, the meaty one... What does the neural network mean?

(Note: This is not 100% accurate, it's just an explanatory slide from a presentation I made on the topic.) 

I've gone back and forth on including more info about the network graph. Initially, the input and output neurons all had their own labels, but it was really cluttered and hard to read. What I've been thinking of doing is adding just a few icons identifying groups of neurons (for example, the visual center on the top right is 5 neurons; so I'd just put an eye icon that encompasses all 5 of those rather than labeling each neuron individually.)

I'll keep pondering and possibly add some more explanatory information to the HUD in a later update.

Thanks again, and enjoy!
