Good job! Game was simple and it works which is always a plus in my book.
a few things I've noticed:
1. while playing is the difficulty remaining static throughout my entire playtime. As a result, I had to let myself get hit by the sparks to end the game and stuff.
2. The sound is quite nice. One thing I would suggest is not starting over the music whenever a player is navigating through the UI so they don't have to hear the beginning parts of the music over and over again in rapid succession
3. The arrow indicator that let's me know where a spark was coming from was helpful but I found myself looking in a small area in the middle of your game rather than looking all over your game and seeing whatever cool aesthetics you game has all over the screen
4. the upgrade of the magnet was a really nice touch and the explosion of particles when the magnet dies was great as well!
