Cannot equip anything. Developers abandoned this app

I would give 5 stars if the game worked properly. Everything is fret except for not being able to equip items purchased. It seems to be a common issue in the reviews. It looks like they abandoned this game since they havent updated it in two years and the link to the website tells me there is a error and it no longer exists.. So I dont think a fix is coming which it too bad because they have a fun game here and it only has one minor bug to make it perfect.
