Myself and several friends were playing and streaming the demo last night, and we had an absolutely BLAST, each of us picked a different class, played off each other's strengths, and got to enjoy a ton of laughs while we figured out how the game fully worked, and we LOVED the puzzles (please keep them lol). Overall, I think its going to be one of our favorite group games.
We did notice 2 things that impacted gameplay on Odin Shell. I'm not sure what I did to cause this first one, but somehow I ended up having a full stack of ores (I think Tin?) showing as being in my hand, and the stack was in inventory slot 2, but inventory slot 1 was selected, and the tin ore became inaccessible for the rest of that session. I'm unsure if it fixes itself after closing and reopening the game as we didn't have time to continue, and won't be able to play again together before the demo closes.
The second bug we noticed was one that actually only impacted one of the players. The rest of us could easily see the spots to grab and launch ourselves up to the platform where you can feed Odin Shell, but the fourth player couldn't even see them without having her cursor pointed directly at it.
Outside of those 2 bugs, we had an absolute blast and cannot wait for the game to come out!
