I like the idea, and am impressed with what you managed in 96 hours! That said, I do feel more could have been done with the gameplay. It feels very repetetive, and there is no real strategy in which spell is found next (if you could walk back for example, to an altar where you can choose/switch between either 3, that would have made a good addition). The graphics itself look good on an individual asset base, but combined do still feels lacking consistency (as you said you were targetting graphics, i'll base my feedback on that), the characters feel very incosistent with the world style. And the world itself feels very empty. Just a big path that I follow for too long (I did see the variation in the houses that were added, but didnt feel enough). Maybe next time looking into more procedurally generated (not realtime, but more like heightmaps generated offline for use of more organic terrains)?
It's still a big achievement with what you have done. Don't let my feedback get you down, take them as words to continue developing your skills!
