It's a great game! I like the old arcade feel it has. It's simple but challenging and I like that. The art looks really good, I'm really impressed by what you made. It's the star of the game imo. Everything looks good and well integrated. The apartments and the individual rooms that you enter have a great design! They repeat a lot but because of how well they look it doesn't really matter that much. It's a treat to look at really. I also love how the grainy FX makes me feel like I'm watching myself from a security camera, maybe that was the idea!
Adding a score like "money stolen" would be good to challenge yourself to get higher and higher! Or maybe "apartment complexes cleared" as well.
