If the player has previous experience on platforms, probably yes, it is. If the player is not an expert, it would take more time, maybe double. They may fall  on some big jumps and had to retry some parts 1 or 2 times. That's my guess

Would you say. the game was too short?

It's kind of short... but, for a 48hs jam it pretty descent (I've played shorter games on one-week-Brackey's GameJams).
Of course if you have more time, you can expand the current level or even add more levels. But for a Jam it's just fine.
