Very impressive game considering you made everything yourself from scratch. The sfx were pretty fitting, and the music was interesting to listen to as well. The pixel art was pretty well done and pleasing to look at despite not being too complex either.
There's a bug where I can just lift everything off the conveyor and they'll just disappear without me losing lives. Having a system where they snap back to the conveyor or something would prevent this. Screenshot below.
The music, albeit pretty nice, unfortunately didn't loop for me, or it just stopped for whatever reason which was a shame.
Gameplay wise, I only wish there would be more of a challenge since for the most part, it never really got too difficult for me. Making the conveyor faster in the later levels or adding even harder challenges with more tools required to detect counterfeits would be cool. Having an infinite arcade mode where the conveyor slowly gets faster and faster is another possible addition that I think would add to the game. The concept being displayed, however, I think is pretty neat and definitely showcased the potential of such a game.
The story was pretty neat but the spelling made me feel like I had a stroke reading sometimes. For the most part I could still understand what the boss is saying, but I had to reread some dialogue a few times, so try to keep the intentionally (I'd assume so at least) bad spelling at a readable state.
Overall, had a quite a bit of fun playing this one.
