Thank you for playing our game, I'm glad you're enjoying the story so far. As for the full release, the reason this game is feeling incomplete is because this is actually the first installment in a series of episodic games. Each episode will be more or less the length of this one with improvements to play experience and story development. We have already released the second episode "Friend Zone: Pledge", you can play it here: Friend Zone 2: Pledge!
As the artist of the game I'm glad to hear you like the designs, MC is a favorite of mine (she even has her own clothes and hair customizations now!) I personally really enjoyed creating the designs of Roman and Remmy💘 💜
The coder @beastcarving has stated that as the story develops, so does will importance of the choices.
Thank you for following the Friend Zone series and we assure you the game is receiving regular installments, our third release is set for June, we hope to see you there!
