Thanks for playing and leaving me a sufficiently explained review!
When the theme of the jam published. I can only think of some platformer game with hidden traps. Yeah, it's suitable for the theme but not unique and innovative. So, I couldn't get an idea that satisfies myself for the first two days. Why would people tell lies? It most likely is because of money. Boom, this idea came out. A bad guy is being good to you but he will take over all your money at the end.
I set the target as 300 coins because I think somebody may find the correct way to play the game for the first time.
This is the first time of participating a game jam on my own. I'd learned a lot more than I expected.
