Fun game!
My best strategy so far is to mash all the buttons every time he drinks, so that my drunkard does not become fish baits. On the second level, my brain.exe crashed.
It took some time for me to notice that there is a drink meter there, I think providing a drinking sound effect would give players a heads up beforehand.
I have a reflex of a cactus. During switching, I need some time to take in what has happened. For us cacti, keeping the direction they are walking or change them towards the safest direction using raycast would help send more drunkards home.
