I got to 59 meters! I could probably have gone further, but those enemies sure like to latch on! Are they faster or the same speed as the player? Because I noticed that once they touch you, they will never leave your immediate side. Making them just a little bit slower, or maybe adding a damage knockback would help with that.
It took me a little while to realize you were supposed to walk to the right, there's no visual indication in the background that you're actually moving. Just a quick tiled texture and maybe some milestone markers every now and then would help the player know that they're doing the right thing.
Nice job! I hope you keep jamming!
