Pretty good, though it bugs out either when you buy an item or when you RESTART and go through the store's door because it gets stuck on the dialogue with the cashier.

It seemed to bug out for me when i attempted to purchase an item a second time. First time opening the shop screen, no problem. But second time it bugged. It got stuck on the item shopping menu. The NPC talks about a cursor being missing and then i couldn't find my cursor to close the shop screen haha. Escape key didn't work.
