Thank you! I'm happy you liked it
I'm still getting the gist of some things, like the music (today I learned that I could've just installed a soundfont on the software I was using to get that chiptune feeling of the 80s and 90s games XD), but by the time of the jam I wasn't even aware of what I should learn.
About the map I really hoped it wouldn't be needed, but as you and more people here mentioned it was lacking and something I should have prioritized, that's good for me (the person who designed the puzzles and map) to keep in mind not to make assumptions about the player being able to solve hard puzzles or keeping track of the game's map by memory.
About the buttons I reckon it would be a good quality of life improvement and I confess I considered making it but don't really know why I didn't implemented it.
