You have my highest rate for Visual & Theme. Really well done on that front. But the platforming needs quite a bit of work. It just doesn't feel right.
Of course, there are a few bugs, like pressing "ESC" when the menu is open makes you unable to move, but those are par for the course in a short game jam like this one.
Overall, it is a very good game and if you expand and polish it, you can publish it and have good chances of finding a target audience.
