Post-Jam Update!

I've added some polish to the game as well as some new content and a menu. If the game was a little bit too difficult before, you can now also play with less dice if you want. That will hopefully make the bosses a little less tedious :P

Changes:

• Added main menu.
• Added sound and difficulty settings.
• Added a boss-rush mode.
• Added a dice training mode.
• Added some polish and minor changes in many areas that should hopefully make it a little more clear what's going on.
• Fixed some tiny issues with sound and enemy behavior.
