Okay, so I ran into the crash again, which means the fix is likely in the backer release (version 0.22.78).
I don't have money to spend right now… I got money for my birthday recently, which was to buy a capture card, which I bought (and can't use, due to software and hardware complications).
I may not get money for a few months…
But it would be nice to have an optional minimum price on itch, where you can get the backer version, and all future backer updates if paid for the game, or choose "no thanks, just take me to the downloads" to get the public versions.
I know itch supports that type of thing; and if people think they'll like the game (or have played the public release) they can pay more than the minimum to give you more support; though at that point they might as well support you on Patreon for other possible bonuses, if they want those.
Just something to consider?
