Unfortunately not the whole room is visible unless your screen is 16:9 or wider, causing items to leave the screen...
It's possible to get them back by dragging a box along that side of the screen, because they are just outside of view.
I'll make a new build to fix that when the voting period is over...
Glad you still enjoyed it! Since it's a puzzle game we wanted the player to figure things out, but some more hints or instructions would have definitely helped...
