Very polished! I like that you get to see the goal at the start. It gives you a good idea of how well you’re doing.
If I had one gripe with the game, it’s that the auto-scrolling camera makes your life kind of difficult in a few spots. You have to go to the left a bit partway through the level, and since the camera speeds up as you move further right on the screen, it cuts you off on the left very quickly even if you were well ahead of it before entering that section.
