An amazing entry, and to think this is only your first game jam is crazy! It's a very ambitious project and one that I would definetely want to see more off! The theme was more than well addressed, and besides the little bugs (such as dragging a dice right in between the two slots to get double damage hehehe) and the font that is a bit hard to read, you have a full game with several fights and scaling enemies and an upgrade shop(with unintended consequences)! Very good job! :D
