Story is awesome! Liked your cutscene in the beginning of the game and voice acting a lot!
But, the game is... meh. No, concept is nice, but the game isn't done at all. It looks like you just didn't had time to complete all of your ambitions.
I had fun fighting with that interesting monsters, but as is went up and up, the game became more trolling, and less actual game, at first i tried to complete everything, but at the end, when i saw the level, where there was only a thousand of monsters, i just became angry. There wasn't any invisible wall, and i just skipped it and went to the room with the potions, or something like that. Did i had to break them all? cause i alt+f4 after that and don't know if there anything else.
You should try to make this game more complete! The story is intriguing! I would like to see this in its final state in the future!
Pretty good start, especially for your first gamejam. Just, in the next try, do less and polish more maybe?
