### 5/5 — Great game but problem on smaller tablet

*2022-03-27*

On my larger tablet the fish at the bottom are available for clicking to place them on the play board, but on my mini iPad the fish at the bottom AREN’T THERE. Excellent game. Glad I played it with success on larger tablet 1st, so I knew what made play impossible on my mini. Thought you all would definitely want to know. Please fix so that players can access the “fish”. Thank you!

**Developer response:** Thank you so much for your feedback!  I'm glad you're enjoying the game!
I'm very sorry about the problem on iPad mini. Unfortunately I was not able to reproduce your issue on the latest iPad mini 6th generation, it's working fine for me. I would be happy to troubleshoot further if you want to contact me https://castoutapps.com/home/contact/

### 5/5 — LOVE this game!!
