Good job on spreading out the learning curve between the game upgrades!
I feel like there's some interesting meta-commentary here on how each "upgrade" is still entirely a game of chance, just a game of chance that's more obfuscated so you don't realize that it's all chance. Feels like a soft takedown of a lot of mobile and gambling games, lol.
I also liked the integration with texting your friend, that's a nice touch.
