Little note for anyone else who might not be getting Shards of God to download at first: I just clicked the "download now" button and it didn't do anything at first. This, when other itch.io games have been downloading without much issue.
I for one was able to get it to work by clicking the button itch.io provides of "Downloads not starting?", and then ticking the box for "alternate download mode".
The box prescribes this for if itch.io is blocked by region, yes, but it also worked for me even as other games have downloaded well enough. Anyone new to itch.io like I am, give it a try.
Mr/Ms/Mrs. Vávra, no hard feelings I hope about a newcomer blabbing troubleshooting input here on the storepage.
