chill man it's not true what are you saying, they are working to release a demo.
I can uderstand your concerns but i followed hentaku's work since the beginning( even before subscribestar page) and he truly wants to make a good game but they are just few people (2 or 3 max) so they need time.
I'm not saying that you must give him money, that is your choiche and nobody is forcing nobody, but before say that he's a scammer let's wait for an actual demo, obviously the more money he do the faster he can release things.
i believe in this project, so before judge i'll wait
