I can understand that you may be a little burned for all the erotic visual novel and parody games that are in Patreon. This month I saw 3 BIG projects fall.
But again, it's just a Teaser, not a Trailer, not a Demo. Of course, you may not like it and adopt a mistrustful attitude about this project.
I am not going to tell you "please, believe in me, put money now or otherwise it will be too late". Of course not, I wouldn't believe myself either! But the message I'm trying to send you is something totally different. Something like: "hey, I'm here, this is what I can do, something is going to happen, get in the loop. If you like it, do whatever you think, if not, well, you didn't lose anything".
