I ended up going into negative money. Maybe make the 'Go to Shop' buttons clickable, or make it clearer that you need to move the player to the area first. Otherwise, it's really nice!
I kept going back to the main menu, and it wasn’t until the third time that I figured out it was because of the wall. Really good game; it definitely has potential. The second level was a little frustrating, lol. Maybe instead of resetting the whole progress, have it restart the level instead.
