I love the idea, I feel so uncomfortable having to choose my own body part to use as bait. That aspect alone is absolute cinema 10/10. I was cringing (the good kind) doing that, and the gore-y visuals are also very nice!
The fishing gameplay is disappointing, especially after reading the description. I was hoping for it to be maybe a minigame, where if you fail, you have to use another body part, but a success lets you cast for free, using what you caught as bait.
Because as is, you choose a body part, click to cast, click to catch when prompted, and then you repeat the process.
There is no 'balancing' the desire to catch, as you don't have any control beyond choosing a body part.
Also, you can drag the value of the bar at the top-right. I don't think that's intended, but it confused me.
