Hello
Holding right click while moving the bopper is meant to hold the fish once you collide with them. Please let me know if this doesn't work.
I wasn't able to get the instructions widgets done in time (started late). I tried to get the instructions on the game page, please check if you want.
I didn't think of someone going into the water, I thought everyone would go into the platform only. I'll keep it all in mind and fix after the jam.
Thanks for playing :)
