While I love that Home Alone movie. This game does a fairly nice spin on it, traps are put onto a conveyor belt, but I think it could be better by having options to put it with what you want or need (Then again, it's game design leans into timer-based game).
It could've have modes to have one player do the traps, just to see a thief by itself go through traps and get the treasure (Or with a role of a thief, generate a random trap that you either must avoid or go through).
Somewhat flawed being that you could put those traps around where a bandit could spawn. And that it's goal is to find the treasure when you're the thief, which can be placed outside of the map for all we know. Though another issue being that you immediately get a treasure to place even if you're holding a trap. Maybe place a warning or a reminder that time's up.
I should add music's a bit unrelated to the game, techno in a middle of a Christmas night seems unfitting.
Anyways... It's negatives are apparent and are flawed in their way, but it has a nice interface, niche game design, varied traps. Map's complex and has enough hallways and rooms that you could place traps into. And it has nice art, simplistic in a niche way.
Briefly: Web-game adaption on a 1990 Home Alone movie (Only with a generic criminal instead), alas biased but it has that unique game design, interface and a nice look.
Two and a half.
