I'm cutting Crushstation a break because he's constantly updating us on his progress.
Not saying you shouldn't, hell I'm a patron so I do think he's actually putting in the work, but
if it was a scam, he would also update us constantly.
By updating a lot, he gets around 4K per month despite releases being few and far between. I remember when that Tropic guy (Incredibles trainer) dropped off the face of the earth and only popped back every few weeks/months, his Patreon cashflow dropped a ton and quickly became close to nothing.
And before you say "but if he's releasing things every now and then, that proves it's legit", not really. In many cases with Patreon, the issue is that the monthly payout encourages the creators to drag out the development of whichever game they're making if it appeals to a lot of people for as long as possible, because if the next project isn't as successful their income will sharply drop. For an example, look at Akabur's income over the years. Sure, he still makes 5k a month, but back when he was working on Princess Trainer Gold, he was pulling 10k a month ! He hasn't dropped off the face of the earth, Star Channel is quite good and quite liked so far, but the fact that it appeals to his patrons a bit less still halved his income.
So in this case, Crushstation
could very well be lying about how long he works on it everyday,
could be lying about how long he thinks he'll need because he knows there's a big chance that once Female Agent reaches near completion, he'll find himself with less money coming in and will have to convince "us" again to get on board with his new project to regain a similar level of income.
Once again, I don't think he's scamming his patrons and BS-ing everyone. But do NOT dismiss that possibility because he's updating us frequently. He'd have to be a terrible scammer to blow his "cover" like that.
