So cute! I didn't figure out how to gamble on upgrades until a second playthrough, but it's a fun extra mechanic! Only thing that feels missing is some sort of end game. Even without upgrades it was pretty easy to get hamsters running all wheels, and then you are just keeping things running for as long as possible. Would love to see some huge upgrades I could save up for, to give me something to keep playing for. That said, well done! It was a very charming game.
