Thank you so much for letting me know. I've contacted Jam organizers and am hoping to update the download link to include the PCK. I'll let you know when/if I get this fixed so that you can play!
Just played it, was awesome :). Although as the other comment said, it is kinda annoying how the monsters are locked to each room, so you don't have too much choice with who to match. Still, pretty cool!
Oh haha, might wanna put this under the description of the game just in case someone else gets a lil confused as well. I do hope more people check out the game tho!
