Thank you, and go ahead take it :) I noticed the audio thing too. We use FMOD + Unity so something in there I guess. I'll have to try some stuff.
As for balancing it's a tricky one. I usually invest in gold & defense early, using attack to go for challenges that seem doable, and then building up for a big attack with one or more attack mult tokens and praying to lady fortune that the crab doesn't take it away. I dont win every time, but I have bested the crab.
There's a feature we don't explain properly where you get 2x the current round in gold just before you enter the shop - so 14 gold on round 7 - so it's not just the crab that powers up as you go.
Anyway, thanks for the feedback! I'm pretty happy with how we used our time during the week, but maybe balancing is the thing that could have used more attention 😅
PS. The following (real life) items help: Rabbit's foot, horseshoe, four leaf clover
