Awesome feedback thank you. I'm glad you could tell we did put a lot of work into such a simple game. 50hrs of development alone, not counting art, story and sound time.
I plan to address your concerns. I've already added for the next version, a quest task on the screen and adding a mini-map as well. The artist is working on walking sprites for all the npcs as well and I plan to address the collision objects like you pointed out. Along with your other feedback. Thank you!
