Pretty good game although I did notice a couple of mistakes with spelling and stuff but that doesn't really matter much.
A couple of suggestions that I'd say are shouldn't the guards be able to move up and down between floors to get enemies? There's no point having 6 or so guards BELOW the final enemy. I also agree with adding the ability to hold the frost bolt key instead of mashing it?
4/5 for me.
