Hmmmm.... i may have got a bit lost in playing this....
But seriously, congrats on something that not only grabbed my attention this long but also just held up to being pushed way past what i think its intended limits were!
The mechanics of this were unique and fun and really well implemented. they worked well together and felt really tangible. Scanning the items felt good and the stress meter felt tense! Everything worked well which is a little surprising when physics mechanics are involved! 😅The upgrades felt varied and fun and allowed the player to try for differnt 'builds'
The graphis were cute and nicely implemented and everything felt like it fit together along with the music and sound effects. everything felt like it was doing its job really well and all working cohesivley.
The main star of the show however has to be the polish. from the music speeding up, the little flash of the items as you scan it, the customers faces, everything i did in this game felt good and had some feedback. even just the rare upgrades being a differnt colour was a nice touch. All these little bits of polish make for a really nice feeling entry that feels less like a game jam and more like a demo or even just a level of a finished game. Really great work.
I think any criticism or feedback i could offer would just be around balance and content, but i think given the context of the time frame you made that in its not particularly helpful because you did a great job on those parts when you consider its made in 2 weeks.
