Thanks a lot, super happy you liked it!
Great ideas, we had some discussions about and vague plans for adding stuff like progression/unlocks, but in the end we kind of ran out of time and had to focus on getting the basics sorted out...
But I think it could really be elevated by adding some kind of reward loop and progression – maybe we'll look into that in the future :D And more sounds makes everything better I think!
