Castle V Castle is snappy minimalist card game with robots, witches, and sentient doomer signage
I can't be certain, but the music for Castle V Castle sounds very much like it was made on an old Roland TR-808 drum machine or equivalent plug-in. Your ears will be familiar with the 808 even if your brain isn't - it's about as ubiquitous in hip hop as the Amen break. That's actually quite fitting, because this minimalist strategy game has the rhythms of a call-and-response rap battle. That's something you could say for all I-go-you-gos to an extent, but the bellicose back and forth here is especially sizzling, snappy, and scintillating. (The game music is very different from the trailer music.) Read moreRead full article on Rock, Paper, ShotgunPress Coverage
Castle V Castle is a new turn-based strategy game funded by a Slay the Spire dev
Take the single-player card battling of Balatro and drizzle it lovingly over the strategic castle building of Age of Empires, and you serve up something like Castle V Castle. Inspired by classic browser game Castle Wars, this clever new turn-based strategy game from solo developer Nopopo and publisher Future Friends is funded in part by Slay the Spire dev Casey Yano (via the Among Us team's indie publishing arm Outersloth), and it has a free demo on Steam that you can try right now.

Welcome to Castle V Castle!
Hello everyone! I’m Folmer, a solo indie dev running a little studio called ‘nopopo’, and I’m working on Castle V Castle, a stylish turn-based castle battler where you reduce your opponent to rubble in a magic-fueled duel of wits and bricks! I’m so excited to bring you the first public demo of my debut game on Steam! Since we’ve never met before, here’s a little more about me: I am Dutch but currently live in Valencia, Spain ☀️ I live with my partner and two cats, Digby & Parker 🐈 My last project was Devolver Tumble Time 📱 Casey Yano (famous for being one of the lead developers of Slay the Spire!!) is funding this game via Outersloth (the funding body born from Among Us creators Innersloth). Thanks for making my Castle dreams come true 🤌 I chose my dev name because ‘nopopo’→ no police → no rules 🚫 I may or may not be banned from the United States🤷 Now we’re acquainted, you can go ahead and check out the demo, add CvC to your wishlist, and follow on twitter and tiktok for more updates! Thanks and talk soon! -folmerRead full article on Community Announcements (Dead Meat)
