Thanks! Now that you say it I feel kinda silly :)But still I might not be the only one who doesn't see it.
No problem :). Yeah it's good to know if it's at all mistakable. An addition we could make is like maybe some visual feedback that the fish is blocked, like a bonk-on-head sort of thing if it tries. Thanks for the feedback!
Definitely not your fault if it wasn't clear to you. My apologies for that. Thank you for trying and providing feedback.
