Get coins by heading outside and shooting slimes! After you buy a gift, the shop refreshes every 3 days
Is there a shop other than pip? She has only offered to sell me the lobby upgrades and stock hasn't refreshed in over 10 in game days.
To the left of Pip's head/chest there is a green arrow to take you to the gift shop ^^ in the next update I'll make this bigger/more noticeable!!
