Woow I loved this one. I want to do it justice in my review so I'll break it down into a few sections.
Audio: Sound design is on point, like menu select, dialogue blips, etc. Music gives this such good flavor, makes the setting fit right in with the sardonic grimy world of Sam and Max.
Visuals: UI is classic Game Boy with modern polish. Nice use of linear perspective in the shop. Character sprites are highly expressive, the merchandise is easy to read. Skillful use of color to indicate time of day through the window lighting. Palette based fade in/out in scene transitions and on the merchandise after transactions.
Gameplay: The gameplay loop is easy to learn, and quite fun to haggle with the customers. I see there are the foundations for time/performance pressure with the "family" man, and a risk/reward system with the hot items system. If the game ever gets fully implemented, I could see myself killing a lot of time behind the counter. The UI is a little complicated when getting started, I got quick advice in Discord. To be fair, the How To Play guide explains it pretty well, if you read it 😅. An optional tutorial round with the family man would be peak design, call it my wishlist item.
Overall, this is one of my favorite entries this jam, and earned full marks from me in all categories. Nice work. Can't wait to see what else you guys cook up.
