The concept of being able to craft your own hiding spots is brilliant, I just sooooo wish it was conveyed how long it takes to actually make a vase, or even where the security cameras stop. It took way too long
As a fellow GameMaker developer, I would suggest using the draw_healthbar functions to make a visual representation of when the vase will be finished, and maybe use the dark flooring to indicate the range of the cameras? Just some ideas.
I will say that I did have fun playing it, and I applaud you for getting it done in the time limit! Solid effort!
