yeeeaaaaah it is a problem. Mods are generally strict with the length of the map, and 54 is too long. By the looks of it, you could probably shorten the map to 40 jumps or less through simplifying the tower and utilizing slime/water/minecarts/anything that doesn't require jumps to be difficult. You could also buff it to medium difficulty, where 54 jumps is perfectly acceptable. This is just my advice, though.
