When I saw the promo for this, I thought it looked fun. And it was even better. It's literally the most addictive game I have on my phone now. All that time you put into the making of this was worth it. Edit: Is there any way to save progress? If not, would it be possible to add a way? I kinda lost my progress when switching to a new phone ;-;

Thank you so much for the nice review! Transferring save files is a tricky problem. Either I would have to pay for servers and make it account based or allow players to download and load save files (this could lead to account selling or cheating). Until the game starts returning a profit its unfeasible. <3

I saw this on the indiedeveloper reddit. Really loving it! I've gotten to the second biome and I love how I can just pick it up for a few rounds and go! My only suggestion is to add a chart with the fish value? Maybe the museum section?

Glad the Reddit post translated to downloads, haha! Great idea on the fish chart! I just released an update that revamps the museum, fixing the UI and adding fish rarity labels to help track values. Thanks for the feedback!
