Tried building it on HTML5 but it didn't work, I think I'd have to recheck everything I have done as HTML5 is stricter about the syntax of the code and even then I'm not sure how many problems there exactly are in the current state of it. I can get HTML5 working on another freshly started project but not here. As for Mac, I don't own any iOS devices so it's quite impossible to do that either. But yeah I couldn't upload any more builds here on itch.io during the jam even if I wanted. I'm afraid you'd have to get hold of a Windows device to play this.
