Beetle & Expire - 2 INSANE Demons [GD] 

Another custom mappack done!
Skill Insanes pack:
Night Terrors - INSANELY HARD DEMON (when I beat it on 60hz)
Beetle - INSANELY HARD DEMON
Expire - HARD DEMON
Expire is definitely the easiest of the three.
At the time when beating it (and on 60hz) Night Terrors was the absolute hardest level I had beaten
The first completion of Beetle took me about 500 attempts total and it took around 200 to rebeat, so rather easy, but it was on 144hz so yeah
