I like the concept and the whacky worldbuilding! The car felt pretty good to control, too.
I’m not entirely convinced by the hiding mechanic; on the one hand, it makes a lot of sense, on the other hand, it sort of slows down the pace of the game and leads to this weird situation where it seems like the optimal strategy would be to hide in every bush you encounter. Maybe just having to collect sufficient mangos that you can throw at the frog to bait him away from you would work? I also thought the tell when the frog would arrive could be a bit clearer, though I do like the subtle screenshake effect.
The music was a very nice fit for the vibe, nicely done!
