Hello, thank your for playing and for the feedback! This is the first game that I actually put out so I appreciate any tips like these, I'll keep them in mind and update it :)
As for the part about running from invaders, it'll remain an important mechanic at the beginning of the full game, so I do think implementing a tutorial for it into the game itself is a good idea, as it might be pretty frustrating to get captured without even knowing you could run. The next parts of the game are probably going to be more choice-focused though, rather than focused on running away.
