I'm so sorry I did't realise you already commented at the JAM and I already replied to you. :D
It's been one of those weeks for me.
O I comment on both the jam and game page. A short something on the jam page as a highlight for other people so they will click on the game too. And a longer critique on the game page for the creator.
I don't know if the jam page stays up after the jam but the game page will be up as long as the creator wants it to be so I figured its beneficial to comment on both.
