The moment you max that thundersword *intro riff to Rhapsody of fire - Holy Thunderforce starts to play* :D
Okay so silly joke aside i really had tons of fun playing your game, and the fact that you made a full on upgrade menu system with this many spells and all for a jam game is really impressive :O
I just had some initial hiccups, i wanted to try through the web version but i had a strange bug, i properly clicked in the game window upon start and all to make sure the mouse input worked, and i could click on menu buttons and all but in the tutorial i couldn't shoot the fireball spell when asked to no matter what i did so i'm not sure what happened there :/ so i took the download build.
So other than this oddity with the web build, i had no other issues what so ever, i had a good time, i love the art and music, and i really liked the fact that even if you fail you keep your points so you can upgrade and have an easier time upon retry.
You did really well, congrats and good job ^^
