Nice entry! I did finish the game.
There was bit to long wait before entering a new command, this could be done quicker to not let the player lose interest of a locked game with predetermined enemy attacks. The riddles were easy enough but fun. Harder for non natives though. the 15 atk spell I had to look up on internet to figure out.
The general scope of the systems and levels are suitable for a jam. So good job at the scope.
