Yeah, same here, I couldn't even get past the title screens. Which sucks because I really wanted to play it. My phone has 3GB of RAM, and will handle a lot of games on here, so I'm not sure it's that, could be, but it is a Renpy game, so I dunno.
So I just got to the end of the demo, first off, be still my beating heart with Veronica, holy cow. And Vex too! Anyways, everything worked great, but I couldn't get to page two or further in the save file slots because the dates were coving the page numbers. Everything looked great. I'm very much looking forward to seeing more!!
