Hi,
We're very happy that you like the game so much! Any kind of support is welcome! I wouldn't count on "more games" as the very rough estimates for this game is at least another year of development, but dev didn't say he won't create another game in the future.
Take care and have fun playing REC! If you'd like to know more about the game I highly suggest checking out our Wiki page and joining our Discord server for daily devlogs, dev streams, sneak peaks of upcoming events, supportive community, chance to request some features, add a custom comment to the in game chat and many more!
Cheers
