Hey, I just wanted to say, this was seriously the best Hammerwatch map me and my friends ever played - even better than both the main campaigns. We all agreed!
The only problem we had (and it was big enough that we would have quit if not for this forum post) was that confusing button mentioned above. We had no idea what to do there and looked everywhere else and were about to give up with the map until we did a google search.
It needs a hint of some sort, like "you need more weight" or maybe a sign that says "A life is gained by those who work together", or maybe both. I think even still it would be a pretty hard riddle to figure out. We actually had 2 people stand on it at once before we figured it out but there were 3 people in our game. Maybe if you had multiple people standing on it but not all, it could say "You need just a little more weight".
There also might be a bug there. When we finally figured it out and everyone stood on the switch, there was two messages that popped up at the exact same time so we couldn't read them. I think one of them said something like you're not heavy enough. Maybe you have a hint but a bug keeps it from being displayed until afterwards?
Other feedback we had was in the very end when you get trapped in the cage for a conversation, we had a hard time triggering that and were confused because it took a long time before we all 3 were down there together. We often wandered around separately. In addition, some doors were hard to see or find because they were on a bottom wall and not marked on the map. Maybe they could have a longer carpet leading up to them? Or something on the map if possible?
Anyway, AWESOME job and we loved it. THANK YOU for making this map! It was amazing!
