Could you open pre-orders early? You would get the money from all the people who are going to buy TLF no matter what sooner.
We could, although in past experience that's something that is unlikely to bridge the gap unless there was visibility on the Steam storefront. We could easily raise a few thousand dollars taking your suggestion there, but we need closer to $40k gross. Because of... math complexities... if I pull the money out of my back pocket it's more like $20k that we need, if even that, to bridge a month.
But either way, that would be very unrealistic expectations on preorder performance based on past preorders; we'd have to see something like 5x higher sales than we've ever seen before during a preorder period. Which is certainly something that could happen -- I mean, anything is possible, really, when you're talking about loads of people like this -- but the likelihood of that being a full solution is pretty low.
But it certainly might be part of a larger set of steps that get us to a full solution, and that's what I was referring to with an open beta -- the sort of open beta where anyone who preorders it gets into the beta, basically, like we did with almost all our games prior to I believe Skyward Collapse.
