We planned to add a Control menu screen, but time beat us (I'm saying that a lot xd). In the meantime we put the controls in the itch.io description
We had a lot of mechanics in queue but at some point we had to prioritize bug fixing, balancing and game flow (also it would have been confusing because of the lack of sprites). The current habilities are the pill and the drone. Playing with light seems interesting... oh wait you meant illumination haha
