Hello, Leg Fetish
Thanks for your kind words. It's mean to us.
Itch.io doesn't have a subscription model - it's mean you buy just one build of the game. Future update's are not included.
If you are intrested in future updates you can look at our patreon or subscribestar subscriptions (low tiers starts from 2$ per month).
We need a subscriptions because the game are in development on crowdfunding base. Half our team are working and live by subscription donations: Dr.MAD are quit his regular job and made creating projectATMOSPHERE his work for a living. You can read more about it in description above "Why should I become a patron?" part.
