Ok so I made it past that part, but the difficulty just ramps up way too quick from then on. I made it to the next letter but I quit trying to backtrack after. There needs to be at least one or two checkpoints in that part.
Having said that, this game looks and feels great! I'm not sure if you did it or not behind the scenes, but you should definitely track how many times the player dies and possibly even display it on the screen while playing, at least as an option!
I'm not really sure about the lack of music. It's interesting because it makes it feel lonely and rough and matches the aesthetic, but at the same time some future techno or ambient could do a lot to fill the space so to speak.
Great entry!
