It's another entry in the Launch-Earn-Upgrade-Repeat genre. If you've played the Burrito Bison series or similar games this will feel familiar.
If you've ever asked yourself the question, "What if I was playing Burrito Bison but instead of crushing gummy bears I was crushing cars on the highway, and what if the overall production value of the game was a bit lower?" then this game would be the answer.
I don't know how it ends. I stopped playing when I noticed that my runs tend to earn a few hundred, maybe a thousand dollars if I'm lucky, and the upgrades costs several thousand dollars. The game was just too grindy at that point.
Not a bad game to waste some time with, but if you've played some of the better ones out there, this one will get boring real quick.
