When I tried to download the original The Kite I got this:

It sounds like the website with the game isn't set up properly or had some sort of glitch.

If the problem persists, you need to contact the itch.io technical support.

Not sure which url you were at but anything with "upload" in it can't be right.
You should be able to get the free game from

It is only for Win64 systems, so make sure your CPU is a 64 bit type.

I can't run this game on my 32-bit system but did check to see if the English version would download. The download seems to be working.

Is this the version you were trying to obtain?

I just followed the link on the original post.
