Just a small recommendation, if you didn't call it the Tutorial, but rather "Story Mode" or something like that, I think less people would think it was something to drudge through to get to the "real game". I really enjoyed it.
As of now, there are still places where you can't navigate fully with just the keyboard. I would recommend binding everything to keys, so the user doesn't have to switch to the mouse often if he wants to use the keyboard.
So I finished the insane difficulty on my first playthrough and I have a couple of suggestions regarding the Magic side of the game.
1) The game starts off a little slow. Perhaps start the player with a spell or two to make it more interesting.
2) Make a Magic Attack Stat like there is Attack, so the player can make attack spells more powerful. They don't level unless you pick up a new one.
3) A spell that shields you for a given number of hits would be useful.
4) A spell to slow down opponents would also have been helpful.
An addicting game once you get hooked on killing the monsters, but there wasn't a great sense of satisfaction at the end. 8/10
There are quite a few ways to level farm, especially when mummy kings are summoned. This broke the game quite a bit. In addition, almost all levels were beatable by just spamming the archers.
In one of the dialogues in the cave you used the word retarded. I don't think this is the best word choice, since it will definitely make some people angry that you used it.
I have a complaint. On the hourglass level I didn't start the level with falling down the side. Rather, I started with a jump directly down the middle. While this made the level doable on the first run through, it made it undoable on the second run. Not difficult, undoable. I don't know how this could be intentionally avoided but it is quite annoying since I cannot finish the game.
