Loving this game! I'm finding myself wishing I had it on my phone too, for when the Playdate isn't convenient -- have you considered an Android port?
Awesome! I'm glad you're enjoying it.
This is actually a port of an iOS game I wrote a few years ago. I changed the rules quite a bit to better fit the casual nature of the Playdate, but its the same general concept.
That said, I unfortunately have zero experience with Android development and no access to a device for testing, so the odds of an Android version are not good. Sorry!
If you have a spare moment, I'd really appreciate it if you could rate the game!
