Thanks for testing! Version 0.7.4 fixes the crash and adds auto equip for picked up items. I'm not sure what to do about inventory management, but I'll figure out something to show the held object info for version 0.7.5.
Thanks for playing. The blinking things are shop tags that stay on items until they are paid for, hopefully they look less like numbers now. The amount customers pay has been adjusted starting from Version 7.
Thanks for the feedback. The rabbits and sound effects will be better in future versions, but the door opening and customers visiting while in the shop has been added starting from Version 7.
Thanks for playing, I hope you found it fun overall. It's not meant to be cryptic but it is a not-Earth shop. The stats need fixing; the rabbit happiness should be dependent on how much they eat (70% hay, 20% veg, 10% fruit) and other rabbit stuff.
The tab thing was added to highlight interactive objects (like in isometric RPGs in the hope that it would help those players out) but the UI could be made more intuitive. Thanks for playing.
