Thank you so much for the feedback and positive comments!
I actually toyed with the idea of having a silhouette of the Moon/Earth depicted somewhere to give you a basic idea of where you were. That was too hard to complete in the time allotted so we opted to go with an arrow showing you where you came from. I agree the memorization can be tricky and I'll keep that in mind as we further expand on the idea. Thank you again!
EDIT: I'm glad you liked the art! It wasn't surprising at all to us that that's where we're receiving the most criticism, though. It's definitely an area we were both lacking in but we tried our best and didn't resort to outsourcing, so we're proud of what we came up with and we're not upset that it comes off amateurish (because it is!). We hope to slowly get better at it as we get more experience.
