You might want to pack the .exe, .pck, and the .ico into one zip as it seems that the .exe needs all of them to really function at its best and being able to download all of them at the same time would make getting into the gameplay a bit easier. I believe you can upload new builds and whatnot so it shouldn't be impossible to put in after you read this.
This game is certainly rough around the edges, with the menu, other ui, and general assets working but aren't the most intuitive or readable. The menu almost looks fuzzy, and most of the text on it is hard to read because of it. The sound effects/music are charming but having a cleaner loop of the music would make the slight pause before it loops around again a little less abrupt.
I do however rather like the spell merging as after getting a hang of it it really started to show me the interesting part of the game. However the gameplay depth mostly ends there. Overall a very good first project, but there are certainly things to improve on.
