Yes, sadly I did not have enough time to do the final test before publishing.
The game has couple game-breaking bugs, yet they are so incredibly simple to fix, that I'll do it and publish the game (out of the jam) as a full release.
Thanks for the good word about art and music - I made sure to tell my friends who created it about your comment!
And yes.. the game balance is dead. No testing = no way of trying if it's balanced or not.
Thanks again and have a good day!
