For a first publish I think it's quite good.
I will note some things you could change/add for future updates:
*A score counter that counts in one direction for how far right you've gone+High Score leaderboard
*Give power ups their own sprites, maybe a 'How-To-Play' tab explaining stuff to the player.
*Speaking of, a menu would help.
*The SFX are cool, but this game could really use some music
*Add some small progression in obstacles? (Add a color swap when you reach it and add new things to deal with like saws or spikes or something? A good example of this is Kawaii Run)
Fun overall, but I wish it had more uniqueness
