The title screen is a wall of parody game covers, all hand drawn, and it's the best thing here. PAYWOMAN, ROAD TRAFFIC ACCIDENT, "the last one remaster", "ball game this year" sitting right next to "ball game NEXT year" (which is the annual release joke in two words). It's a chaotic, funny collage and every cover is a small jab at the industry. "the last one REMASTER" got me.
Choosing Ren'Py to build a shop simulator is an unexpected call and the result has a handmade quality I liked. The boss character, a giant smiling pink head in a purple suit greeting you with "welcome my dear empleoyee", is crude but has charisma.
And your description is disarmingly honest: "if the game doesn't break, post your stats in the comments so I can see how unbalanced it is" and "I might fix the game, or maybe not, I'm tired". That's pure jam spirit and it genuinely made me like the entry more.
Things to fix if you do come back to it. The title screen has a clear rendering artifact, the covers appear mirrored and duplicated in the middle of the screen with the text reversed, which looks like a transition effect that got stuck. There are several typos ("empleoyee"). And the side menu (Start/Load/Preferences/About/Help) hides behind the covers and is nearly unreadable, which is a problem since it's the only way into the game.
Messy, and you know it, but that wall of parody covers is worth the visit on its own.
