itch.io

i am new and paid for this game on affect3d website it downloads but then says network issue and then it says couldn't download something went wrong try again or contact your organization so if i am not the only one having issues why do this have a problem of downloading this game should download like every other game and it doesn't and it said everything i said in the beginning 

for me i just saw it on itch.io and was interested and when i played it i was amazed by it very good game 

this game like the  beat em up games but i thought it was going to be more characters in this game but i can say that this game is amazing should have a story to it i love it, my question though is will there be more characters or just play with the female?

question is the steam version going to be different from this version or is it going to be the same? i paid for it on here is why i am asking

i have paid for this game on itch.io do i have to buy the game again if there is updates?
