Well, nice idle game even thou I don't fancy this genre. However, somehow my save have got deleted and probably I won't play it anymore. A shame it doesn't have online save feature :/
It would good if you would make this game longer, add some more upgrades, maybe skill tree and some survival mode for example. Also bigger variety of items and some more complicated story and quest system. Anyway game seriously cought my attention and it says v0.5 so keep calm and carry on :)
It does have a save system. Reload the page, if you lost your saves, you will get everything back again.
