Really requires a tutorial, but I figured it out! For others playing, you need to find ways to dirty the car. The first way is to make the dirt into mud.
Good presentation overall!
Weak marks for theme because it's only backstory. You have a goal - dirty the car - and that's it. Dirty = success.
The timer makes it a puzzle how far you can get, which is good! But I got to the frog in the toilet and ran out of time, and I didn't want to do the bits before that again.
I feel mixed about this game overall... but it's one of the most interesting I've played. Good job :)
