Yeah, it's kind of fun - very easy (my kind of game, lol). The current Dcity prez pointed it out to me last weekend...I'm a sucker for these types of games.
You should definitely program that; now is the time! I keep thinking about all these NFT / play to earn games are out there, but the simplicity of use, player appeal, stories, characters, ecosystem of Splinterlands really makes that the one people really enjoy. If I could program something, I'd definitely follow that type of model.
