Very nice idea! I liked it!

- The visual effects.
- The SFX
- Background music.
What I didn't like?
N/A
Bugs:
- "WebGL" version of the game, the in-game text is unreadable. (I can see just half of it, when I play the game on full screen, and when I don't play on full screen the first letters of the text I can't see it)

Suggestions:
- Use "Text Mesh Pro Text" instead of the default text.
- The pause menu is empty, write on the top of the pause menu "Paused".
- Add a score and a high score.
- Scale down pause menu window.
Great work! Keep making games, and never give up!
