If you’re trying to play on Mac, try right clicking on the app after extracting and select “Open.” macOS by default blocks software from running when downloaded from the internet by default, but selecting Open may let you bypass the block.
with newer computers, this doesn't work. it only works on old computers
Put the .app in your user/USERNAME folder an then execute (in the terminal)
chmod a+x mac.app/Contents/MacOS/*
Or you can just use the itch.io app.
it doesn't seem to be working with the app either the install button is replaced with an open page button which takes you to the website
Oh well, it's just a short jam game
