Metroidvania with a car? 10/10 for the concept!
Atmosphere? Amazing
Jokey post-apocalyptic billboards? Spot-on
Critisism time!
The car idea was underutilized, I would have love some more speed!
It felt a little easy to me, but this could just be personal preference because I am God gamer :P
One last thing:
With the fat cat defeated hopefully the trash planet can return to peace!
Good job!
