Which version are you trying to download? - I've just tried the PC version and it's downloaded okay. I can provide a mega link but given the game size and mega limiting it to 5gb dl (for free) I switched to google drive (even though it's slower).
It's the PC version. It may be something to do with me trying to download the game at 2:30AM, realising I didn't have time and cancelling it, then trying again the next day, something may have cached badly on my PC. I've tried clearing caches and what have you it, but no luck. I have however managed to download the file using my phone, which seems to have worked. Need to get it transferred over and see if it installs properly. I'll reply if I get it sorted.
