I enjoyed playing this, especially the open world feel of the locations with their semi-secret areas. The heist concept is innovative for a dungeon crawler, and the alarm system adds tension...or panic, in my case! :-) Graphics and audio are good and create the right atmosphere.
I had to visit the office twice to make the 10k, so it was nice of them to restock all that cash! :-) Then made it as far as the truck, but was unable to lift the stands and got caught by the cops. I really liked the multilevel, maze-like layout of the construction site, that was fun to explore.
My only minor suggestion is to have a few more tips initially, e.g. about needing a tool to pick locks, and perhaps a prompt to look at the notice board on the back of the door.
Great game, thanks for submitting!
