I recently discovered my love for pawn shop games, so this was right up my alley! ;-)
Your game didn't just nail the theme and the bargaining mechanic, the atmosphere is on another level! The soundtrack, the lighting, the tiny window, the whole run-down vibe, and that passing train create an immersion I haven't seen anywhere else in this jam yet. Things like the upgrade mechanics are just the cherry on top!
Truly outstanding work!
