Why not put the full game on here instead of makin people wait
its just the way with small/indie games. A lot of one man, or small teams posts a beta/alpha and see if people are interested. It's kinda how some devs like Poppy Playtime found huge success despite my personal opinion that the story is kinda bland.
Sometimes you or your team can only have so much passion or money to continue development. You also want feedback for future development.
