I've installed this game both through Galaxy and through the installer, and each time there is no apparent app bundle to launch the game with, just a UNIX executable. Is there some reason that this game was not released properly as a MacOS app? Please fix this.

Still waiting for this to be fixed.

I am also having this issue, did you ever get it resolved? I just submitted a help ticket.

Wow, almost three years and nothing. Just bought the game, what a shame…

Try opening Terminal and drag the file named deadcells to the Terminal. Press enter and the game will load.

You can try restarting Terminal if the game quits for any strange reason.
