would appreciate instructions on how to open with mac, i see an exe file and a document called HS Strife Project_MacOS that i can't make heads or tails of

Here's what you have to do.

1: rename the HS Strife Project_MacOS file to Ikemen_GO_MacOS

2: Run Ikemen_GO_MacOS

3: Type this in terminal 

chmod u+x 

Press space so it isn'tlikethis and then drag the Ikemen_GO.command File so It'll create a path.

4: Open Ikemen_GO.command and it should work.
