Okay, the game is absolutely adorable, I like the powerups and general mechanics.

Physics takes some getting used to. Pretty nice concept overall

I think this is a great idea, an original concept. Just one thing, the psychics of the car jumping are weird sometimes. I think it could be fixed modifying factors as floor normal and stuff like that.

For the rest of the aspects, it was a good job! :)

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!
