Hello I tried to download the game but it won't allow me to downa nd this is the error I get. I am downloading on a Windows PC. 
This game contains files compressed with the proprietary Deflate64 algorithm. This is not supported by the itch app at this time.
I recommend that the developer recompresses the game without Deflate64, or even better, uses https://itch.io/docs/butler/ to upload it.
