You should download the whole game here; it's in two parts. Please let us know if you can resolve this or need some help.
Hi, thanks for the reply.
I could not download it on the app, it said 'cannot read property 'build' of undefined', whatever that means lol.
It only downloaded the patch.
Then I tried to download it on itch.io in browser (on browser? not sure which is correct, sorry=) ) and it worked.
I still can't open the game through the itch.io app but apart from that I can play now!
