Very good game!
Nice work on this game. On the one in the building, the items don't respawn once you take them. You might want to make the screens a bit bigger, since it's pretty easy to fill up. You'll also want to create an erase button since it's easy to fill up the whole screen. I noticed how you only put certain items on certain maps. You want to have a collection of all the items. You need a back button, too. But great job, and I look forward to seeing an update to this game!
