It would be nice to have some strategy for running your merchant shop that players buy/sell from like each type of ware could have its advantages and drawbacks. This is only a base for something bigger and more fleshed out in the future. You should stick with it :)
This is a good submission; however, it was difficult to know how to solve these levels since you have to deal with so many mechanics at once. Also, the player's pathfinding was getting stuck in a few places, but otherwise, great job!
