what is voxeljam? 

voxeljam is a contest that is going to last 18 days this is a competition  to see who has the most talent in making Voxel related games.

This is made to be a fun and competitive event. Harassment is not tolerated but criticism is accepted

And try to make the platform for mac if it is a download as i do not own a windows computer if its in the browser it doesn't matter. but if you cant i still will try my best to rate the game, if you already started it for windows continue doing it as long as there is a video of the gameplay
