Thank you very much for reaching out.
On my end, I was able to download it without any issues using the PC app.
The cause is still unclear, but I’ll continue looking into it.
Thank you again for your report.
I’m truly happy to hear that you’re enjoying the game.
Receiving feedback like this is the most rewarding part of developing games.
Thank you so much for your kind comment.
Please look forward to the next update :)
If everything goes well, the latest version should be available in early access sometime in May.
