  Our next game is live on Steam: Casse-Croute Deckbuilder

  Hello everyone!After Hamstermind, we wanted to explore a new kind of strategy game, something with cards, combos, food, and a lot of weird tactical decisions.So today, we’re happy to announce that the Steam page for our next game is live:Casse-Croute Deckbuilder Casse-Croute Deckbuilder is a roguelike deckbuilder where food is your weapon.Fans of Slay the Spire, get ready to drop your weapons and pick up your forks.In Casse-Croute, you build a deck of powerful food cards and kitchen tools, manage your hero’s Appetite and Cholesterol, and fight your way through the Burger Kingdom.But since this is coming from the team behind Hamstermind, we couldn’t make a deckbuilder without making it a little bit puzzly.Cards are not just played from your hand. They appear on a dynamic board, and your movement, path, positioning, timing, and resources all matter. Finding the right combo can feel as much like solving a puzzle as building a deck.The last 2.5 months have been packed with intense work. The timing is very tight because we want to take part in Steam’s Deckbuilding Festival on May 4, so we had to go all in and work twice as hard.If you enjoyed Hamstermind’s puzzle logic, hidden depth, and strange little systems, we think Casse-Croute Deckbuilder might be for you too.Wishlisting the game helps us a lot. Sharing the page helps even more.Thank you so much for supporting Hamstermind, and for giving our next weird idea a chance.See you in the Burger Kingdom.

  The last puzzle difficulty adjustment

  Adjusted the late-game puzzle difficulty because nobody in the world managed to solve it… and I like when games are actually doable 😅.

  Stability Patch – No More Walking in the Air

  Bug fixes Fixed an issue in A1 where the player could walk in mid-air. Fixed an issue in D6 where it was possible to go above the level and get stuck. Updated a chest combination to match a newly discovered optimal solution (don’t try to understand, you won’t). Fixed a reset issue in A5 involving two boxes. Special thanks to many members of the Discord for reporting these bugs. I won’t list all your names here, but you’re in my heart ❤️
