A surprisingly fun little game. Really nice pixel art, the transtition effect, the clock, and the bag were all really well-done, too. I also liked how the music seemed synced to the clock.
I only have two fairly minor issues. For starters, the zoomed-out version should be the default, or failing that, zooming out the default a little more. There's too many blind jumps on the zoomed-in version, which is a cardinal sin of platforming.
Secondly, I really wish the "thief" angle was played up more. Like maybe have the game set in a bank instead of a sky grassland, and adding in security cameras and policemen as hazards. For now it just seems like a regular platformer.
Overall, though, the game was really good, and I'd definitely like to see an expanded version. Just be careful with the Nintendo assets, though!
