Damn sorry to hear about the crashes, ill be sure to look into them!
The 3D assets and all of their textures were designed, modelled and painted by me, yes :)
And yeah the filter on the game is very much inspired by lethal company!
Also it is possible to make the rebellion win but there are some conditions you need to make sure.
(SPOILERS AHEAD!!)
During day 6, if you pass any contraband that Isn't The clover, you will still lose. It only tells you to pass the clover, and the other contrabands are unrelated to the rebellion's plans, that might be why it failed.
I might make that clearer in a patch tbf
