Who knows man. When it comes to downloading games off of steam or other official apps, sometimes that pops up. I've downloaded an app before and my phone says its VERY dangerous but ive used it for 4 years. Up to you if you're going to download now or wait for the reply of the creator. :)
question. Is the vampire girl in the demo? If so how to trigger event. Also please answer my previous comment on specifically when this game will be on steam. If its still undetermined sorry for making this comment look something like a complain or something馃槄.
