Hello!
My name is Eetu Rantanen, but online I often go by XeduR. This site is a code portfolio: Solar2D games and tools, game jam entries, and a handful of other things I've built in my free time. The source for most projects is on my GitHub profile under the MIT License.
I'm a game designer and full stack developer with over 13 years of professional experience. Most of what's on this site is built with Solar2D and Lua, and a good chunk of the games are jam entries from Ludum Dare and Global Game Jam.
I'm also fascinated by data and analytics. I have extensive professional experience with data, from building end-to-end pipelines to statistical modelling and turning raw data into insights. In my free time, I've data mined plenty of the games I play, and I genuinely enjoy talking about and teaching data and statistics. That's how I ended up as a visiting lecturer of business mathematics and statistics at Estonian Business School in Helsinki from 2018 to 2023, where I got to share my interests and hopefully nudge a few students to look into the field themselves.
You don't need to credit me for using any of my projects, but I'm always happy to hear when they've been useful to someone.
Games
These are some of the non-commercial games that I've created over the years in my free time. These games do not include any of the games I've created for my clients or other commercial projects.
Gone Diggin'

Roso Games / Learn Solar2D
I'm also involved with Roso Games, which is a free, remote game development project where beginners learn to build and publish games together using Solar2D and Lua. It's run by the Finnish non-profit Kukunori ry and has already shipped several titles on Roso Games - Itch.io.
The project is currently only available in Finnish, but we are working on expanding it globally and open sourcing the learning materials so that anyone can pick up game development, Lua programming, and the Solar2D engine.
Widgets, libraries and other unassorted things for Solar2D
These projects range from individual tables or concepts to more complex functions and systems. Essentially, these projects come in all shapes and sizes, but I either didn't consider them big enough or distinct enough to turn them into plugins.
Autotile
Touch a cell on a grid and Autotile figures out which tile to place and updates all connected tiles automatically.
Tech: Solar2D, Lua
Weaver
A narrative and dialogue engine for Solar2D with Twine 2 integration for creating branching stories and dialogue trees.
Tech: Solar2D, Lua
Morph
Morph allows for simple creation and scaling of display objects and their physics bodies in Solar2D.
Tech: Solar2D, Lua
Performance Meter
A customisable on-screen meter for tracking FPS, texture memory, and memory usage in your Solar2D app.
Tech: Solar2D, Lua
Print to Display
Print to Display adds a console to your app, making it easy to view prints even while testing on devices.
Tech: Solar2D, Lua
