The art is very cute and I am seriousely impressed by everything you have managed to make in just a week.
Jingeling the keys was funny at first but this method of movement quickly got pretty annoying. just holding the button down for example would have lowered that friction somewhat.
The Boss works really well for the kind of moveset the player has, which is nice. Combat was fun in the beginning but some of the later rooms where you could not hide the King very well felt more like luck rather than strategy.
The level design was also pretty good.
All in all it is a great packe. You can be very proud of this game. Such a smooth overall experience is something you usually don't see with game jam games
