  Tokyo Game Dungeon 12 Exhibition Report

  On May 3rd, 2026, we exhibited at Tokyo Game Dungeon 12 with two titles: "Card Collect (tentative title) (Super !! Card Collect)" and "Ruku's Heart Balloon." This was our fifth event exhibition (2022 DigiGame Expo, 2023 TIGS, 2023 Picture Book Festa, 2023 Design Festa). As it had been two and a half years since our last event, we prepared for this one while recalling the good and bad points of our past exhibitions. {STEAM_CLAN_IMAGE}/44827339/43fa6afe06e90a0bf3d6474ac520676b3dc891c9.png Playable Demo: Ruku's Heart Balloon Already available for purchase on Switch, Xbox, and Steam. Since it was featured in the INDIE Live Expo's GAMES ON SALE broadcast on April 25th, 2026, we decided to offer a playable demo for the first time in a while. Based on past experience, we had three playable units. The demo featured a free mode (a mode where players can freely play puzzles) rather than the story mode. Everyone enjoyed playing the puzzle for about 10 minutes, exclaiming, "Wow...! It's really deep!" {STEAM_CLAN_IMAGE}/44827339/28880c80def5423a5b85dc34edf17356bf5f5968.jpg 70 people tried the game! We explained the story mode to those who played the puzzle, showing them the picture book. Some even bought the book! At our first event, the Digital Game Expo, if my memory serves me correctly, we had 36 people try the game... This time, we had significantly more people play! {STEAM_CLAN_IMAGE}/44827339/fbe04d1a4305a69ef67b717ed3e7a0ec01c79524.png Exhibit: Card Collect (tentative), Super!! Card Collect Since it's a game where you endlessly open TCG packs, we created a POP display similar to the original packs sold at card shops. People looked at Ruku's and then at the Card Collect display, saying, "What is this...?" We distributed a promotion where you could draw actual cards from a card vending machine by registering on a wish list, and 20 people registered on the wish list. {STEAM_CLAN_IMAGE}/44827339/80f42fd6d13189d2c4b097365715040a3958ac7f.png INDIE Live Expo and Tokyo Game Dunge...
