I enjoyed this game, I thought the gameplay was nice and it had a cool core loop. I think this would have good potential as a mobile game with the simple control scheme. If you choose to go this route, I advise adding in more types of obstacles and some sort of progression system.
If you wanted to improve, I suggest having the obstacles despawn after a period of time, the game appeared to have problems finding new places for obstacles to spawn after enough were on screen. I noticed they would try to spawn in then would despawn as soon as an error was found. I recommend having the old one despawn and keeping in the new one or repopulating the old one so there is always more points to be gained.
Overall you have a solid foundation and I hope you keep working on it.
