Hi, I try to download and run the game on my MacBook, but it says 

The application “Ocean Ephemera Mac” can’t be opened.

Could we have a WebGL build to play in the browser as an alternative?

Hello. Sorry about that. Mac builds are difficult to run due to strict security rules and an expensive notarization process required by Apple. This workaround may help:

I can look into making a WebGL build, but the way the game works, I don't think it will be optimized or optimal to play through a browser.
