Hello Stella,
There were supposed have a explosion sound effect to explain why there were boulders on the way but for some reason it didn't get in the final build. About the movement keys we will definitly work on that. We wanted to put some enemies to confront the player and also another area to explore but we didn't have much time left before the deadline. But the moment we come back to this project after being more experienced we will improve it for sure and put a lot of content. Thank you so much for the feedback and for playing our game it really means a lot for us students that we are :)
