### 2/5 — It won’t let me in

*2024-04-08*

It won’t even let me in. It’s like glitching so bad I can’t even get in it and I don’t like that. Can you fix the app please? I don’t know what the problem is. I keep trying and trying and trying. It won’t even let me in.

**Developer response:** Thank you for bringing this issue to our attention, and sorry for the inconvenience it caused. We just released a new version that addresses this problem.

Hope you enjoy the game!
