WOW this game was amazing. Already blown away by the title screen. Such nice pixels, graphics, earthbound-like groovey battle background art, music, and the gameplay mechanics of washing a car + undertale like battles is such a fun and unique combination. This was really peak slick.
The only constructive feedback I had at all was that:
1. I wanted to be able to see my timer when I was battling, I can't tell if it was a web bug but it moved up and was hidden out of screen so I couldn't tell I was close to game over (maybe that's an intentional move to make it more suspensful), and
2. every now and then one of the sludge creatures on the car was directly under a "switch directions" arrow, but I was able to just click near it and drag the mouse over to clean it up.
Such a good game!!!
