Short answer... yes.
Long story... Today is the final day of a Kickstarter to fund my next game Rainbow Laser Disco Dungeon.

It's not going well. I had some kind of breakdown last night and embarked on a... perhaps misguided attempt to save the glitchy robots from that dungeon by hiding them is this game. They're evil trans-dimensional beings, but they're also my children and allowing them to pass out of existence altogether... well... it was just too much for me to take. I'm not really used to anyone playing these games, so I didn't figure anyone would notice. They are really bad robots though. I'm sorry they freaked you out.
Disabling the audio with F5 should have disabled the robot voices. That's a bug and that's on me. I will fix it today. I'll also work on separating out the robots onto a separate toggle so you can turn them off separately.
I'm so sorry. I love those robots and I'm really sad they won't have their own game. I can't just cast them out into oblivion.
