The first Playdate game that I purchased and sideloaded onto my console on the day that it arrived. And I still play it quite often!
This one isn't just full of spirit, but it's also really fun. Plus, as highlighted in the description: you can pet the dog. And that's what I'd like to call a selling point!
It took me a couple of days to beat the Story mode of the game, but there's tons more to discover after that and I'm not done on that front yet. But even after, I see myself coming back to play, just because of how fun it actually is.
PS: I love how Playdate devs have effectively established this dog cult. It's just awesome!
