The game is now easier than previously, mostly thanks to enemy damage scaling with your level. There are still some things that need to be tweaked, of course. To mention a few: Guardians and Atlases benefit from standing behind a low cover (this will be changed), Guardians' M-358 Talons are probably too deadly (they use the same version you can find), and Devices objective is hard as hell.
And then there are bugs to be fixed, things to be polished, and features to be added, etc. For the next release, I'm planning to add five more playable classes and a proper mission failure/success screen that lists your accomplishments. Floating combat text, too.
Also, the thing with the game not launching might still be there. I haven't found the cause for it, and it's unlikely that I've fixed it by accident. Running the game in compatibility mode may help, though.
