if you find the gem and it collapses at the same time the game softlocks
I thought I fixed that. Are you sure you are using the last version?
I was using the browser version and I was searching for the gem and I found it as it collapsed and the game turned all black other than the mute/unmute button.
ive done it before and that didnt happen. But I'm using 3.0.2 on scrolling through like every comment so...
