Honestly the best way to support the game is probably through the bounty system. Here’s how:
- Go to the issues list on the github.
- Find something that looks interesting, or that you feel should go into the game.
- Click on the issue, and on the bottom of the first post you should see a link that says either “post a bounty on this issue” or “there is a $X open bounty on this issue”. Click it, and add to the bounty there.
Then we get the satisfaction of completing earning a little money for helping the game, you get the satisfaction for having helped out with the overall development of the game, and everybody gets an awesome new feature or bug fix a little bit sooner than they would have normally! (And if you can’t find anything that looks good enough for you to want to stick money up for it, then you can always feel free to chuck into one of the already existing Z-levels issues bounties.)
