It's a good game. It's procedurally generated, so there's a lot of replay value, although the downside is that there's no desire to get as far as possible (other than beating your high score). Unless I'm mistaken, there are no new mechanics introduced the further you progress (e.g. a new type of enemy once you pass the "100" mark).
And since you seem to like arcades, consider adding a scoreboard to your games – it's much more compelling to attempt to beat other player's score than just your own.

About the choppy movement mentioned by another reviewer – I agree. It feels slow and isn't fluent at all. Just trying to get up takes forever and falling back down isn't super fast either; luckily you move on your own, so you can take the time you need. Check this gif to see the problem:

The problem with "zip through" ability stems from the fact that you can't always clearly tell where you're going to end and sometimes you just needed to stop a little bit further (or earlier).
The movement problem could be, in my opinion, improved by making you simply move UP if you hold the spacebar and fall down (with a slightly larger gravity) when you don't.
And the zip ability could use a (barely visible) guide (a dot, a cross…) marking the place where you'd land if you used it.
