Yes you can get a upgradable house, with total 8 upgrade; you can upgade your house's outside/inside, can own an armory and item shop and a small music room. I'll post more house upgrades in later versions. ^.^ I'm currently uploading new version of game, fixed some bugs and added conversion based side quest in front of Lulu's house, new version will be up in 30 minute. I'm glad you enjoyed ^.^
