For 37 years I've been putting new pillows still in their pillow cases inside of older pillow cases that I had left over.
All of my previous pillow cases were never the kind with zippers, they were just the sheet like material with an opening. So when I got new pillows and noticed there were zippers on them, I always just assumed that was just to get to the pillow "stuffing" or whatever.
Game Title: Bamboo Steel
Playable Link: https://nonchalantpanda.itch.io/bamboo-steel
Free-to-play: Yes
Two pandas in mech suits square off across a single table. Every round is a quick gut-check. You read the shared die, decide which way each card faces, then lock in. Both sides hit at the same time. Out-think your rival, save your ability for the right moment, and knock them from 40 HP down to zero.
This started as an idea for a real board game, the kind you play with a friend across the table. The digital version is step one. If it clicks with people, I'd love to be able to make the physical game someday.
