Hey, I've looked into it, it seems like a Mac OS limitation that we can't really account for. We just pushed a browser-based build if you want to try the game.
If you still want to try the desktop verion, there is a user-side fix for this, run this command in terminal
sudo xattr -rd com.apple.quarantine Path/To/App
Aha! It's, uh... it's pretty buggy (hard crashes the browser, which is just unusual, and I can get it to freeze in desktop program form), but, uh... I'm still giving it full marks because, look at my avatar, I'm 100% the target market for this game, and your style is just incredibly smooth. Those black paint wipes are gorgeous. Is that a prebaked animation, or are you doing that in code with splotches? I love it, I really love it.
Dogs rule!
The black paint transition is a compute shader with a texture. I didn't create it though
