This is a neat concept, I know people have mentioned this before, but it would be nice if the imposter had a random difference, rather than just red eyes.

I kind of like the extreme speed, it makes navigating more of a challenge but it would be nice if it had a bit of a slower acceleration curve so you could finesse a bit more.

Platforming itself needs serious rework; sometimes I didn't feel in control of the character at all. The core idea is there, but may have been used in other way: instead of grabbing a coin, or only identifying the intruder by its eyes, maybe the intruder could have other subtle differences (ears, shape).

Nice idea and adequate realisation, except movement, character moves too fast, eventually I spent my time on struggling with movement instead of exploring level, be careful next time with it. Movement it's a vital part of each platformer.

Interesting concept, I liked the fact that you mixed things up a bit when introducing the need to first collect the "Coin" before being able to identify which one of the critters is the intruder, and since you have one shot it really fits the theme.

However there are issues, first of all the character moves WAY too fast and twitchy ! This makes it very hard to control, and then there seems to be a bit of collision detection issues with the platforms sometimes you can be a bit half through the ground when you land on certain spots. 

I'd say if you want to somehow keep a bit of speed on the character, maybe try to have it build up speed before going so fast this could be somewhat of a middleground between fixing the control issues and not really slowing the character down (although i.m.o it would be better to slow him down at least a bit) 

Despite all this keep at it, it's a neat concept and it is quite fun to play appart from the previously mentioned issues :)

That was an interesting concept you had there. Finding and shooting the odd one? Hahaha, I enjoyed it a lot! There were a couple of problems, though: the controls felt very unwieldy. You couldn't control how high you jump, and the acceleration is too high (I actually think there is no acceleration, it just moves at top speed all the time). This means you can't do any precise movement, since any touch you do on the control will make the character travel a great distance, since the speed and jump height are also really high. Jumping off of ledges was very rough because of the high speeds, and landing on platforms was also rough, since we had to jump all the way and use the unaccelerated horizontal movement to land. I felt like I was fighting the controls all the time.

But yeah, the idea is very good!

among my best games...

Cool, would've been more interesting with more design variations and mechanics, but it's a game jam. Also the game's graphics remind me of Downwell

Similar thoughts to CrustyJon to be honest, although I did quite like the super fast movement speed actually. With the addition of some acceleration / deceleration to give the character some weight, maybe a slowly speed in the air too, I think it could feel quite good. Nice work!

The game is interesting enough, but the whole "intruder" thing doesn't really come up all that much IN gameplay. Sure you have to find the intruder, but it feels the same as looking for an "exit door." The speed of movement is also a bit too fast. Other than that though, I had fun!
