Donations are all well and good but let's be fair, who donates? I've seen plenty of stuff in creators signatures about donations but it would be interesting to know if anyone has donated.
As for a week and a half to make something for this game? It takes a lot longer than that IMO to produce something of high quality for this game.
Some models I believe take months and I've got tracks that I've worked on for so long that I still don't think are release worthy.
My latest track for example, cornerstone took me like a month-ish. Which is why I believe payments would be good because these things take a lot of time and effort
