It would be neat to see some other platforms added. Not sure what platform you've uploaded, but I've seen this before and I'm 99% sure it's for Windows. Not everybody uses Windows (even though that's probably the majority), and making a Windows application run on Mac or Linux is a huge process. It would make the game more universally playable if it's not made for HTML.
Hey, it's definitely something that I plan to do, however, being a solo dev who is also attempting to create assets on Itch, I kind of have to choose my battles. You are right though. Hopefully I can get some other platforms supported soon!
Thanks for checking the game out, I appreciate the feedback.
