Very hard game!
There’s a companion app that you can use to track health and whatnot for free. If you pay $3 you can unlock a digital version of the game in the app.
I’m on iOS so only have a link to it on the Apple App Store. There might be an Android version as well.

If you have kids, the PBS Kids video app is pretty alright. And free (in the US of course)
