Nice chill game!
I feel the score numbers are, with the glow efect,  very similar  the 0 and  the 8.
But overall good job!

Interesting idea! Very clean art style and nice sounds. I love how intuitive it is, I didn't need to read the instructions and could immediately see how to play.

I would maybe add the ability to remove spikes if you get say X coins without a mistake, but even then it it's basically game over as soon as there's a single spike on the screen as there's no control over direction. Maybe it would make more sense to change direction, on collecting a coin, or maybe X coins in a row without mistakes gives you 1x flip ability, so you can manually change direction. That way you could stay alive longer if you've accumulated some points.

I noticed that the random direction changing seems to stop if you play a second game. 

Also at the beginning it's a bit tedious when it's moving really slowly and it keeps going backwards and forwards but never quite reaching a coin before it turns around and goes the other way. 30 seconds of tension lol. 

Overall a great game, very literal use of the theme!
