Like the idea for this game. A few items of feedback:
Is there a bubble that reduces your size? If not, I'd like to see that to help possibly extend gameplay.
Can you vary the music a little? The loop gets a little monotonous
Does your bubble grow by your score or the number of bubbles? Does a tiny bubble contribute less than a bigger bubble?
I get an 'Out of Memory' error after finishing a game.

Overall, I enjoyed this style game. Good job

As @grindkrusher mentioned, the memory usage begins increasing after the game is over.
You can press Ctrl + P to monitor the performance, by the way.

After digging into your code, I found out that in game_over_update() you call parts_init() for some reason, removing that line solves the issue!

And another suggestion, I think it would be great if the player could destroy the spikes while in invincibility mode.

P.S. This game is named "Dancing" in Latvian...?
