I guess something is wrong, because I launched the game, throw the line, and its been 10 minutes.

Hello Redis! Thanks for not only playing, but commenting.
Normal catch timer should be from 10 seconds → 6 minutes.
If you are experiencing longer than 6 minutes please confirm with me.
This is intended to be an Idle game to be played in the background while you do other things. You will hear the sound notification indicating you have caught a fish so you can tab back in to catch.
If you want to experience the gameplay loop you can enable the dev console and turn on 'quick catch' by clicking 8 times on the 'vault' then another 8 times on the 'shop' without clicking elsewhere. ( I am debating making a none-idle version that is faster pace)
