Unfortunately I was a bit clueless in regards as to what to do.
I figured that right click paused the game and explained the controls a little and left click appeared to be some sort of boost.
I was able to move around and bump into things, but couldn’t ‘grow’ or progress somehow.
Overall the game is presented well visually, with nice UI and some good sounds and it’s only a little step away from being a game like experience as most of the work is done.
