Almost right from the get go I was going to complain that the game seemed too difficult, as the tougher enemies were shrugging off my arrows like toothpicks, but having now played through the game, and never actually having lost a level, (Granted I did replay a couple levels to get that third star, so those extra levels probably helped a lot) the game was pretty good! While the tougher enemies can seem kind of overbearing at first, careful use of Magic and Blood Heals makes it all possible in the end.
The magic added a nice strategic element, and made lots of pretty colours to boot!
The most prominent issues that came up for me, were the repeated "Upgrade at the Blacksmith?" popup after every level, and aiming the magic. The Ice spells in particular, Frigid Blast feels like it starts a little behind the cursor and I couldn't quite understand the hit box for the Ice Stalagmites.
