Extremely ambitious obviously, there's quite a lot here. It does look quite nice and the individual parts are actually quite fun. The audio, while not amazing, is serviceable, although there are some parts that are too loud in comparison to the rest of the game. The problem is the game is feature overloaded, and the gameloop is not as smooth as it could be. As previously mentioned split focus is an issue.
Personally i'd strip everything but the spellcasting, or include the potions and the regular attacks in the spellcasting. Then, put the arrows somwehere center, so you can both look at your casting queue as well as still dodge enemies.
For 4 days of work this is incredible for it's size however.
