We'd love any and all contributors! WITWorld is a no-strings-attached side project we're maintaining for fun. So any kind of involvement - game mechanics suggestions, code contributions, etc. - is more than welcome.
We're more than happy to work with first time contributors. Check out the Issues and leave a comment if you see anything you'd be interested in tackling. We'll respond with more details/thoughts.
Otherwise, feel free to open up new Issues with requests or suggestions!
Other questions/thoughts can be sent to tadas [at] tadasant.com.
