I don't know whether the issues some community members have been having with Sundays giveaway (Pahelika Revelations) is confined to the giveaway version? For those who really like the game you can get both versions )in HD) for $1 via the Indie Gala Bundle project. You get a drm free copy plus a Steam key as well.
Both are included in the Hump Day Bundle, which is available HERE The bundle is on sale together with several other games. It is split into two tiers. The first one includes the HD versions of both Pahelikathe games plus one more and only costs $1: (the actual cost of these three games via Steam is presently £20.97 - or approx $31)
Kung Fu Strike: The Warrior's Rise
Pahelika: Revelations HD
Pahelika: Secret Legends
for $4.36 you can also get 10 more games: (The total cost of all 13 games via Steam at the moment is £82.07 or approx $123, that's only 33.5 cents per game)

When it's on Happy hour (it's live for the next day at least) you can get more copies for free. I purchased the bundle last week before it went on Happy hour. I've just purchased the bundle again (to give to my kids), making sure I've ticked the gift box and ended up with four more copies of every game. (You only get these extra copies when Happy Hour is on). I will be offering some of these here sometime in the furture (I've got literally thousands of spare Steam keys from buying these bundles over the last three years since the first one from the Humble Bundle project started back in 2011, so can't say when i'll be offering them as I need to sort the whole lot out first)
