The box contains Holy Dew.
Yep, I was drinking that all jam.
I really like the mechanics around combat - both the "push your luck" of how many enemies to queue up to fight before running back to the arena (that went horribly for me the first time ^_^), as well as the positional stuff, it works really well!
This game was really hard though! This is the first one I've played in the jam that I've been unable to beat even after a number of tries. I might have to come back and try again though... Things were going well on my second run until in one round 3 sneed crawlers ganged up on a fully healed Belsome and killed him, and everything went downhill from there.
Only thing that was really annoying was that, after some party members were dead, I needed to both rotate my view, and rotate my party members in order to read any plaques on the wall.
I like the aesthetics, really nice use of a limited palette.
