This game was a Bullet Heck game which meant you needed to dodge stuff, the stuff you needed to dodge in this game were Stars, The Sun, A laser that appeared on...
To respawn press the "Left Meta" button and there isn't a health bar since it takes one hit to die.
"Left Meta" huh? What if you are using a Chromebook (I don't know what is a left meta lol)? And why couldn't the respawn button be another button like "E" for example?
