Jump feels really floaty and is so short. It seems like it could be a fun metroidvania game but I can't tell because there was so little to see. Make more and I will play more. I just want to see the game in a full form and the art seems pretty well done.

Thanks for that! Yes, the jump could be tweaked some.
As for the length, you often have to cut some things to polish what is there in a jam. Considering this was a one person effort, I think there is a decent amount for the level of polish that is there. I even added a couple of Easter eggs here and there ;)
