Thank you so much.
As for the controls, I've always been a fan of games that leave you alone in a room where you have to use a mechanic to progress, and all they do is show you the button that lets you use the mechanics that let you progress. (Obviously not all games can use this method, but I think most platformers can since they are fairly common and intuitive.) So we tried to go with the tutorial method where the "hieroglyphics" in the background show you what controls you'll need to exit the room, and then let people make use of them to figure your way out. And then throughout we leave similar hints in the background. We've gotten kind of mixed results on this approach, as some people seem to really like it, while others don't, and then there are some that don't even realize there are instructions in the background, and head straight to the instructions on the itch.io page. Which might be a sign that the concept works, but we just need to make it a bit more obvious for beginning players? Anyways, I'm sure there's something for our team to learn here and bring forward to our later games!
