I downloaded this game but did not see an executable like I was expecting. Is there something special you need to do to play this game?
My guess is you need Gamemaker studio 2 to open the yyp file https://datatypes.net/open-yyp-files
It's a zip file. You should be able to right click the zip file and select "extract all" then go into the extracted folder and double click the .exe file. I will update this and change it to an installer to make it easier.
I accidentally uploaded the source code. Sorry for delayed response. I didn't realize the jam separates comment sections from the games page 👀.
I fixed the executable now. Sorry 👍
