Hey, I played your game for a bit!
Like others are saying here, it feels very nice to play, the movement feels responsive. The difficulty also feels fair and increases fast enough to keep me interested. So overall the game is very good!!
I do have some suggestions for maybe in the future, I think in general increasing the difficulty without just increasing the speed would keep the game more interesting. Instead of the game getting faster and faster, you could for example add moving gaps that you have to fly through, or add multiple gaps so the player feels like they need to make a choice. I think this would help keep the game interesting.
Another suggestion I have is to have a leaderboard, it would be awesome to see how my score (I got 34) compares to other players. Adding a leaderboard can be a little difficult, but there are itch.io tools that make it a lot easier (I for example have used this https://danqzq.itch.io/leaderboard-creator).
Overall its a very fun game you have! Good luck :D
