Thank you so much for giving the demo a go ^v^. Lucas' route is gonna be added as a free update to the paid version as a thank you after/if the game sells 1,000 copies. So, unfortunately, for Lucas a person will have to have the commercial "complete" version of the game and lots of other people are gonna have to get it too. We are gonna have contests and giveaways for copies of the paid version on our social media pages later, if you're interested :].
I'm glad to hear you really like one of the guys in the free version. We definitely wanted the free version to be as appealing and worthwhile as possible, without making it so good that no one bought the paid version, of course, aha.
And I appreciate you letting me know about your glitch issues! We're still looking into those ':)
Thanks again for the comment. It's always super nice to see that someone has enjoyed the game!
