Hyakki Yako was a collaborative effort involving 8 members, with 2 specifically dedicated to sound production, spanning a period of 10 months. As our final year project at Singapore Polytechnic, our objective was to create a 3D game. Influenced by our mutual love for Monster Hunter World, we decided to develop a hack-and-slash game, despite warnings about making a game of that genre. Driven by passion and determination, we remained steadfast in our pursuit. Although we had ambitious plans during pre-production, we soon realized our aspirations exceeded our capabilities. Additionally, the separation between the sound producers and game designers posed communication challenges. This experience underscored the importance of effective communication and the necessity of realistic project scoping when operating under client expectations and strict deadlines, despite the boundless nature of creativity.
