The game has a really nice art and audio, helping very much with the atmosphere.
I think it has a great potential for a proper game with level progression fighting minions and final boss fight at the end. Still leaving the choose which level to deal with option.
Two things that could have been done to make the game really stand out, the first one, easier to do, is to give the player the option to familiarize with movement and attack during the level selection. The second one is to have custom controls, but this is something that definitely comes outside a game jam.
I really struggle with the selection of the control used. I would have preferred to have WASD or arrow keys to move, attack with left button and recall with right button. Dash could have been spacebar or rolling the mouse wheel. I am sure I would have been able to enjoy the game more instead of being beated all around by every boss! :-D
Great game and high potential for a complete game.
What I will not do at all instead, is to use AI for text. If you are worried about the language, ask others, definitely you can get great result with it.
Congratulations! Looking forward to see a complete version o this game :-)
