The original concept didn't have the doors or map at all, but it was a thought I had to leverage the coin drop for the doors and it just worked with little to no extra stuff on my part. It is one of my favorite features of the game actually just because of how it works! I appreciate the honest feedback too! I will try to rework the tutorial and the way it comes in. One of the requests I had when friends were trying it before I submitted was that it needed a tutorial because they didn't know what was going on, so I quickly threw it together in hopes that it was enough for people to get the idea, so thanks for letting my know that it might be just a bit too much! I will make it more intuitive and try to slim down the tutorial as much as I can by introducing concepts and letting the player learn before giving them the information. At the moment, it's a bit of a large info dump right from the start.
Thanks though! I appreciate your kind words.
