Thank you!! Especially for your comment on the Gear Pickup SFX, I worked especially hard on that one because I knew it was going to be crucial for the game to feel good. It's like 5-6 different sounds melded into one, plus reverb and other effects added afterward, I think the key element I added was the sound of a coin being flipped. You know that distinct *pinggg!!* It really seals it.
The robots actually do make a whirring, actuating sound when they are approaching you, but unfortunately, I think this one gets a little lost in the overall mix. I'll either have to boost the volume or rework it somehow in an update, it's pretty important to know if the little buggers are trying to sneak up on you again.
Thanks for the great review!
