I definitely got pretty scared by the skeletons when I opened the door, so great job!
The skeletons were really easy to dodge though, so I wish they were a bit harder. For example, maybe some of the skeletons could have a ranged attack? Also, a way to find coins and buy more things, such as speed or a weapon to fight the skeletons, would add some more strategy and be a fun addition, in my opinion.
Other than that, a pretty fun game!
