Neat concept! There was definitely some depth to the game that I missed until I read through other comments (e.g. the fact that you move faster when not shapeshifted).
Worked well enough as a speedrunning game, but I feel like it would really shine if there was a framing story or situation to get me more invested in blending in, rather than just running through the desert(?) and needing to blend each time you run through a building.
Would love to see this concept expanded upon, great job!
