Not bad :) Others have commented already on the movement speed; I would add that the combat feels "mushy" - a screenshake would make substantial difference, so would the hit sound effects. Block seemed entirely useless, because it takes SO LONG to establish it (and in one dungeon it kept de-blocking for some unknown to me reason); strong attack didn't seem to work for me. I ended up with 20 shadow essences and only 2 water ones, when I required 3 to progress - after three dungeon runs :( The drops seemed random, and because the combat didn't feel good - that's where I stopped playing. Still, congratulations on getting to the finish line with a rather complex and feature-rich game where nothing is outright broken!

I love the artstyle and the concept of a dungeon crawling wizard. I don't understand why the walking speed is so slow, I would suggest making the current sprint speed the walking speed. The death sound effect for the first tutorial monster made me laugh, but I don't think it's a good sound if you want to keep going with this game. 
The gameplay loop was cool tho, getting essences on missions to get new powerups. With some more polish to the combat and movement, this could be a really cool game.
Nice job! 

A fun little romp in the dungeons!

• Really impressed with the graphics, character models are solid and environments are pretty good too
• Sound design needs a little work, maybe quieter footsteps but otherwise good
• Combat was simple and got the job done
• Perhaps more of a delay in the shadow spawns. I ended up just running past them to close the portals.
• I found it quite funny continually slashing defeated enemies to hear them continue to groan.

Overall a great entry to the jam, well done!
