This is a really neat concept and I could see some really interesting puzzles and strategy for this game!
The pixelated art pieces looked great!
A couple pieces of feedback:
- I wasn't sure how to use the Space/Shift gadgets? Wasn't sure what Space did and could never figure out how to get Shift to work.
- I felt it was pretty difficult to lose? Admittedly, I didn't get through the whole game though.
- But it seemed like a guard could pick up a painting...but at that point, it didn't seem there was a way to get it back? And I just had to restart the game.
- Having distinct, labeled levels I think would help the player feel a sense of progression as they go through the game
Great work!
