changedMonthly Dev LogWe want to keep everyone up to date on Episode 2 and beyond on development regarding Kumitantei . We really don’t want to remain silent and want to make sure we’re feeding y’all little tidbits of Kumitantei goodness. So, every month, I’ll write these dev logs to share behind the scenes development, highlight different community fan art, community events, and more!
addedExpanding Free TimeWe’d always wanted there to be more to do during Free Time and for there to be more ways to bond with your favorite characters, so that’s something we’re focusing on with the development of Episode 2! There will be two new major features added to this part of the game.
addedExpanding Free TimeOne thing we’ve heard a lot of requests for is the ability to play Card Battle Debate outside of the Clinical Trial, both to try out new Skill Card strategies and see the unique animations for the characters who haven’t gotten to battle yet. We’re adding a new interaction to Free Time that will fulfil both of these! You’ll be able to spar with your favorites during Free Time and wager your tokens on who will win, high stakes with high rewards!
addedExpanding Free TimeWe’ve also decided to bring the “Battle Demo” from the Kumitantei Demo Version over to the main game as a new Training Mode, with expansions to allow using every Skill Card and deck composition against any character you want! We hope these additions will make the Card Battle system more accessible and encourage trying out different strategies before the next Clinical Trial rolls around.
addedExpanding Free TimeThe Prize Corner will also be getting an expansion, including a major rebalancing to the Kitty Catcher and a brand new Prize Shop that will let you exchange tokens for uncommon gifts, upgrades for the Clinical Trial, and even unique Skill Cards! We’re excited to share more information about these gameplay improvements in the future, but for now, we’ll leave you with two never-before-seen Card Battle cut-in animations for Kaguya and Nisuke!
