What do you mean by "stopped working"? did it crash? I'm quite curious
After collected some stuff, right about when I realized I was supposed to collect based on what the phone says (I think), the UI just quit on me completely. None of the buttons worked, (I was in full screen). And it was still broken on refresh. I don’t think this is your fault, I think it’s Unity’s. Therefore I rated the game on the gameplay I got to see. I think I understand the game enough.
Edit: I decided to read the description and changed this post because I realize you play as a collector, you got 5 stars on theme now. (And the UI still hates my browser or something)
