Our best suggestion would be to try launching the gaming using a program called nw.js which can be found at
1.) Download the game .zip file via the MacOS backup link at the bottom of the game description, and extract the folder (Grove_0.204) to the desktop.
2). Download the normal version of NW.js and transfer the app to Applications.
3). Go finder > utilities > terminal and use the following command to launch the game (the "name" should be your username for the file path):
open -n -a nwjs --args "/Users/name/Desktop/Grove_0.204”
If this is all a little too technical, I do apologise. We'll do our best to look into the issue, but... that's a bit difficult when the game just crashes with no error message.
