Just letting everyone know that I was able to finish my 7DRL. I'm pretty happy with the way it turned out.
Have a look...
I tried it out a while ago, so forgive me if my memory is a bit hazy.
I really liked the idea of being more of an observer rather than an active player in the world, having to skirt around the edges of the map waiting for your taser to charge and avoiding all the big dinosaurs. It was a refreshing change from the usual roguelike formula where the player is the center of the world and everything revolves around them.
Currently the ecosystem extends only to dinosaurs randomly fighting each other, I think, but it was enough to make the world feel alive and active. I think with more complicated interactions, this idea could definitely take on more substance and be fleshed out as a more complicated game.
