I appreciate so much your feedback. Unfortunately, the points you mentioned were actually known errors / wrong behaviors that weren't able to be fixed in time for the submission for the game Jam. Also, the reason one of prompts in the cavern doesn't go anywhere is because I forgot to have a room that mentions that the game stops there for now. That's my bad.
We want to work on a lot of feedback mechanics for the player to understand better the combat and to make a tutorial to make it even better from the start.
We have so many plans already for plot points of the story and I am interested in continuing with my programmer friend to make the game a little bit more stable and even finish it.
Thank you for your comment.
