Thank you so much for playing our game and giving us your thoughts! We are college students still learning the ins and outs of the craft, so your constructive feedback is really important not only for our project, but for our growth as game developers.
Within our ability, we implemented a lot of what you mentioned, and added things like NPCs walking around, flags for the checkpoints, and more guiding arrows.
Comments like yours are invaluable and hopefully you will play our future games as well!
