man, that intro... i was in!
just... one little thing...
you cant jump on the entire floating platform. i have no idea why, but there are many of them that when you reach the end, you cant jump off. leading to frustrating unfair deaths that make you have to do the entire thing from the start. This meant, when the music was like... "go go go you can do it, go kill the glowing core!" you had to fight your instincts. I had to literally test every single platform to see if i could jump at the end of it, or if i had to back up and jump from further back than felt natural.
still, i killed the core, and saved the future. i'm proud. you should be too! good game.
