Hi. I assume you can't get steam keys from buying this game on a bundle like the California Fire Relief one, right?

Unfortunately itch tends to disable external keys for large bundles to avoid people buying the bundle with fraudulent credit card info and then selling the keys for a profit. But honestly if you just email me (ponettplus @ gmail) with proof you bought the bundle then I can just send you a Steam key directly.
