Honestly, the price for my country is quite expensive but I haven't found any sites aside from Ideb.io that shared the game from Voltage.inc such as Masquerade Kiss, kissed by the baddest bidder, etc. However, Ideb.io now incorporates the same system as sbenny but in like more expensive way. People can't hardly earn coins but all of the voltage.inc game is like 1000+ coins some even 1600. If buying the coin through Patreon, it basically the same price as buying the game from steam.
