This is a one-man indie effort, which means that there is no dedicated game designer. The game will benefit from ideas that players have about the game.
This made me so nervous, but I guess my first read was incorrect - I initially thought you said 'there is no game designer' and that you were implying that every game design idea would come from players.
Expect players to burn through content way faster than you ever could, and for them to suggest/demand totally impossible stuff with no respect for your capabilities as a dev... but if you have a good filter, I can imagine it kinda working. Hope the controls feel good/interesting though, and that there's enough initial depth to the basic system that people want to play with it for a while.
Good luck with early access!
