I like the visuals and the soundeffects a lot! The gameplay is simple but for a short session fun. I was confued why i couldnt steal the paintings in level 3 (or was it 4) until i saw, that they are greyed out. I think its pretty easy to just run in and steal it and then flee from the guards. So i think a bit of balancing and make them more of a threat would be good.
Love the cover art!
