First off, I like it. I played with the ones that came with it to see what could be done, and I think it's a wonderful start.
I started on a game to learn my way around and found a few things that were confusing, and a couple that maybe might be possible additions.
I know this is alpha so I suspect that there a lot of things to be added, but I was looking for some simple props that are flames, or torches, along with other maybe some tables, chairs, more things to decorate areas with.
When trying to start off a game with a char waking up and not knowing where they were, I added some triggers to spawn a dialog, which worked fine, except there was no option to tell it to do it only once. So a single use switch that is activated by stepping on it would be nice, or maybe a parameter to specify how many times to do it. I could also see a parameter for a number of times before it triggers. Also the trigger arrow to the dialog works, but it doesn't actually show that it worked. I thought maybe I was doing something wrong, but it did work. I was expecting that the trigger would show in the edit what it was connected to, but it doesn't seem to. I could see that becoming more of an annoyance when a lot of triggers are around and you forget which one goes to which items
Another thing that would be nice is the ability to not show areas that are behind walls until the char moves into that area. Think more in terms of rooms. There is the hidden area like in one of the games and I'm seeing how that works.
I'll update with more once I try more things.
