Also commented on Heartreasure2, but want to leave it here as well:
Someone else seems to have stolen your game and is selling it on Steam, with Heartreasure as a free base game and Heartreasure2 as paid "DLC".

You've made a very cute game, please protect your work! Steam doesn't allow anyone but the copyright holder to report infringing content, so only you can get it taken down!
