Looks pretty good and I would like to play through what you have made so far but I can't get past the first skeleton due to input bugs. Basically the keyboard input only seems to work intermitantly. Sometimes it will register if I press a button several times, sometime things seem to be completely disabled. For example I can often not use R to toggle into attack mode even if I was able to do it earlier.
Also, I found lockpicks and several keys that seem suitable to open the locked chests but there is no prompt to try them when interacting. I can't see that I am holding them either, is there an inventory screen/window for that sort of equipment?
Lastly as suggestion. I am playing the browser version of your game on a Mac laptop using a trackpad. I'm left handed and so find WASD plus trackpad controls uncomfortable. I appreciate you including support for the arrow keys to move. How about making Shift + left and right arrow keys turn left and right?
