First of all, congrats for your entry, especially since it's your first sol-dev jam!
I think your concept was very ambitious, that's why there are only a few non-visual video games out there (the only one I can think of right now is "A blind Legend"). Usually, those games use saptial sounds to help players not getting lost. I think it was missing in your project, and since it demands a lot of memory , as well as to remember how much moves are left, it was particulary difficult to get through.
Also since I have an azerty keyboard, it's sometimes complicated to use WASD moves for me. Since you could use arrow keys in menus, I thought I could use them in game as well, but after a while I understood it wasn't working and it was really frustrating.
If you want to improve your game, I suggest you show somewhere how many movements are left, even if you're blinded, and maybe show your path as a line to help visualize your direction more easily. It would be a very nice addition that could make your game very much enjoyable for those who have a hard time remembering where they are. (For some people it's impossible to visualize in their mind because of aphantasia)
Once again, congrats for your entry, and good job for trying to realise a concept this difficult alone in a week!
