Haha, this will definitely be a free game, no worries on that front. Itch.io has both free and commercial games available for download here, as well as some that are pay-what-you-want... Basically, you just have to look at each game's page to know which type it is. :)
Yeah, if I wasn't already swamped with my bigger, flagship title, I would have loved to continue working on this until all the planned content was done, but unfortunately, I'm on a deadline that I have to get back to... Maybe in the future.
Thanks so much for your comments! Hope you enjoy the finished game!
