OMG, evil dogs take over space

Wikipedia:

Space Invaders is considered one of the most influential video games of all time. It ushered in the golden age of arcade video games. It was the inspiration for numerous video games and game designers across different genres, and has been ported and re-released in various forms. The 1980 Atari VCS version quadrupled sales of the VCS, thereby becoming the first killer app for video game consoles. More broadly, the pixelated enemy alien has become a pop culture icon, often representing video games as a whole.

Upgrades / Changes 

- Mistery ship (that red running left-right dog) has 4 random bouses for you. Its:

     1) The power of space gives you a chance to play more, don't waste it (Hp +2);

     2) The power of space turned all quantum reactions back. God, your shields are as good as new again (Restore shields);

     3) The power of space has given you incredible speed, you are now invincible, but it seems that your physical body is not able to withstand this for long, so in time you'll return to your normal state (SpeedUp for 20s);

     4) The power of the cosmos mixed with your dark side. And together they gave you the ability to shoot a DEATH RAY! (Dude, that's seriously a death ray. You'll only shoot 1 time, but it'll be cool);

- Music playlist, change sfx sounds:

   The author of the music is clearly a talented person. You can thank him for his creativity and listen to his other works. https://garoslaw.itch.io/monolith-ost
