Fun game. Impressive amount of variety in game art and puzzle design for the timeframe. All the puzzles feel unique. I liked the glow/lighting effects you had going on around top of the rooms. Being able to pet the cat is a nice touch too.
For improvements, I couldn't work out how to open the nuclear reactor puzzle. I also think you could up the contrast between task warnings on the map and the background; they blend together a bit.
Strong submission. Nice job!
