Even if you donate 2$ more with the 7$ you already paid?I guess it should work!
No, I can't just "add $2". Making it a donation doesn't count. The minimum I can spend is $7. So I either spend $7 all at once for most of the game, or $9 and get everything. I can't just spend $7 and add another $2 later.
Alright, that's really bad
