So you can see for yourself all about the game, it's free. I highly recommend it. 

The game is not natively "full newtonian" but does offer the option to set yourself up thusly, AND it does offer a mechanism (via the unity project download) to produce your own custom maps. 

So this is technically amazing, because it really allows me personally to practice the course theory that I've been bent on in a more refined environment,, along with background music and such. I do have another project you can find on tsmspace.com called "MicroGravityDreams" by Why485 , it's also free, but it's different,, I don't know how to develop games so I took Why485's mini game, and added a bunch of gates to fly through. There's things I could do to change how it plays, but all of it needs to happen within unity, to make separate builds, while Fly Dangerous is just generally more finished , half of the setup happens within the options menu, so it's all around what I play more the last few weeks. (I've only had either one of them from very recently). 

Anyway, in order to play custom courses, you paste a json. There are a few options in the discord, but all of the games maps and pretty much the discord offerings as well are optimized for the native game physics, ,which means speed cap, vector rolloff, and boost (with incredible velocity rolloff). My courses are completely different, and are aimed at being navigational challenges / maneuver

sequence practice for a full newtonian craft. 

I will keep updating my custom courses on tsmspace.com as I make more,, but the present status of collection will be attached here. There is a problem, and that is that in order to navigate the courses according to my intended gate order, you will either have to guess correctly, or watch my "course walkthrough" video for that course. I don't have them linked in the folder,, but perhaps I will try to add that. Ok hold. Ok now there's a document in the zip folder for that. Also there's a document if you're not sure how to use the custom levels, although you can find out from the discord easily. 

Of course you know that my preferred input method is my 4-joystick game controller! (or maybe you've never heard of it, but you can build your own following the instructions on my hackaday page, which is linked to tsmspace.com) . If you make custom levels, I am definitely hoping to fly them! (the discord is a tough way to find levels,, I hope they eventually figure out some kind of more easily searchable database,, although probably that will wait until there is generally more player-made content available. 

It is my personal opinion that player-made courses will drive the quality of navigational sequence challenges much more than developer created courses ever could, because only by accessing the masses can we have the full might of public inspiration to contribute to our maneuver sequence catalog.
