Glad you like the demo, thanks for playing. :)
Well, regarding tutorial text, it was just too much text to display so I decided to tell the player to check the control options instead, which is the best way to check controls anyway.
I have no set release date and I don't know how long it will take to finish, all I can really say is:
It's done when it's done.
As for supporting me and/or the game, it's completely up to you and every little bit of support I get on Patreon is extremely appreciated.
Thanks for the feedback. ^^
