Thank you for your interest in my game. Unfortunately, I don't currently have any plans to build a Mac version as I don't use them enough to confidently test and support one.
However, there are several ways to play Windows games on a Mac. There are several tutorials online to help you with any of these methods.
1) The easiest is installing Wine as they will allow you to run most Window applications, not just games. This is the method I recommend.
2) Another way is to run it via a virtual machine, though this demands a lot more storage space since you are partitioning your operating systems. Note that you do NOT need to buy Windows for your virtual machine to run games.
3) VMware Fusion Pro is recently free for personal use, and is similar to a virtual machine, only you can run this entirely on the Mac side without having to sign out of your profile.
If you do not wish to set any of these up and/or would like your donation refunded, please reach out to support@itch.io.
