Awesome take on the simon-like games! I loved how some of the minor details brought harmony between the theme and the gameplay: being on the lookout for the discounts (although I’m not sure I really needed them? Just like real life ¯\_(ツ)_/¯), trying not to bump into everything when I binge-buy (felt like an actual supermarket run indeed).
I nearly got owned by dropping a necessary item behind the shopping list and then not being able to grab it again, and I experienced some stuttering and noticed flashing artifacts during the transition that hindered my immersion, but well I would not have noticed if the rest was not so polished.
Wonderful job!
