Thanks for the feedback! We are planning to implement objectives being crossed off when completed, that will be in the final game. Missing the general is tricky, not sure how to best address this yet. I don't think we'll do a dedicated healing button, I prefer having all item usage be consistent using the number bar. The reason we have non-interactable objects highlight is because we are planning on making them more interactive (pick up and throw/place etc.).
Thanks again for checking out the demo!
