Nice little platforming game!
The gameplay is quite solid, the jumping feels good, the shooting is responsive (though the shots got stuck on my character one time and I had to restart the level) and the enemies are annoying but not too egregious.
The doppelganger system is quite fun, I liked how in the first level I had to really check out the movement of the humans, I though the one moving weirdly might be bugged, but seeing it be a feature instead was pretty cool
I think the second level was a bit too obvious, the wearing pink clue at the start might not have been necessary, I though the blinking was noticeable enough.
Overall, I liked it, it was a fun, good job!
