Thanks so much, glad you enjoyed playing! The level select sound was me shaking a glass jar full of crystals and rocks, with a little bit of post-processing added in audacity.
The voice acting was done by my bro, who is a true audio wizard. 🧙 He has this to share about his process:
"I recorded it really low and mixed in white noise, resampled it up 2x, then time stretched it 33% slower using e2 transient method in Edison, then put compression > bitrate reduction > high and low pass EQ > dialed in the feedback and stages of a static phaser > and put a noise gate
the ticket was doing two passes with the stretching, you can get more lofi artifacts when slowing down as opposed to speeding something up"
Thanks for the comment!
