Hi there! Thanks for the positive feedback, and for checking in about our future plans.
We have been slowly working away at a very big update to the game. Progress is going very slowly, so don't expect it to drop anytime soon, but we think people are going to love all the new things we're adding.
Right now we don't have plans to bring the game to Steam, but it could definitely happen if we can see there's enough demand for it.
Thanks again!
