Mapperoni: A Tool for Teaching the Basics of Level Design

Mapperoni is a lightweight, web-based educational tool designed to bridge the gap between 2D layout sketching and 3D environment creation in game design curricula. By allowing students to convert simple greyscale images into navigable 3D spaces, the tool enables rapid experiential evaluation of spatial concepts without the high cognitive load and technical complexity associated with professional game engines. The primary objective is to support introductory-level design education by facilitating iterative experimentation with core principles such as scale, navigation flow, and player guidance.

The tool was evaluated through a pilot study conducted during an undergraduate game design course at the University of Jyväskylä in 2025. The methodology employed design-based research, utilizing a combination of teacher observations and a condensed Unified Theory of Acceptance and Use of Technology (UTAUT) survey. While the study was limited by a small sample size of 10 student participants, the findings indicate that the tool is highly accessible and engaging for beginners. Students reported that the application effectively supported their understanding of spatial design concepts, and the teacher noted that it successfully helped students grasp foundational design elements.

Despite the positive reception, the study identified technical limitations, including performance issues on older hardware and difficulties in creating precise heightmaps. Participants suggested that future iterations should incorporate integrated drawing tools, real-time editing functionality, and social features to foster collaborative learning. The research concludes that while Mapperoni functions effectively as a pedagogical stepping stone for novice designers, its future development must balance necessary technical optimizations with the maintenance of its minimalist, low-barrier design philosophy.
