Hello, welcome to Exilian
I liked the second trailer a lot more than the first - fitting this together with the hints of a plotline helped a lot. I think it might be good to get some voice acting on the trailers to give more character to the characters, if that makes sense? It seems to me that, with the relatively simple graphics and gameplay as far as I can see, the important element of the game to get people hooked is the storyline so seeing more on that would be good. Having shorter gameplay segments between the text in the trailers might help too - I often wasn't quite threading together the different bits of text in my head if that makes sense?
Looking forward to seeing what else you come up with though, good stuff
