Ok so macOS-ification doesn't work that way because their app format is bizarre. Luckily, there's other people who have made macOS games with construct, and you can just hack their games to become this game.

Steps:

1. Download this game, unzip it, and find the file package.nw. This contains essentially all assets and code that actually make up this game itself. The rest is the game engine. This is actually a zip file, so you can unpack it.

2. Extract the contents of package.nw into a new folder called app.nw. Hold on to this folder, you can delete the rest.

2. Find another game made with Construct, this game's engine, specifically one that runs on macOS. I found Hardware Tycoon. Download the macOS version of that game and unzip it.

3. Instead of running the game, explore the game files. At this path: hardwaretycoon.app/Contents/Resources you will find another app.nw folder. Delete it and replace it with the one you extracted earlier.

4. You've now transplanted Ooze Odyssey into Hardware Tycoon! When you run the game, it should start playing Ooze Odyssey instead. Keep in mind that it's no longer a signed app, so you'll have to run it as an unsigned app.

Let me know if this works. I don't have a mac to test.
