It's a pretty unique take on the theme, especially since its done in three dimensions. 

The jumping feels awkward, but Elidef covered that better than I could - though I also suspect there's some weirdness going on with the math that makes the jump favor cardinal directions?

I'll be honest, I don't think the reflection mechanic feels good as implemented, at least the way I ended up using it - if I want to go somewhere, I first have to look at it, rightclick, wait for the camera to zoom in, then turn around 180 degrees and left click, and then let gravity to do its thing while I'm too disoriented to know what's happening.

Still, with a bit of work and some tweaking this has the potential to end up as a pretty good Portal-esque FPS puzzler, and I want to give credit for going 3d :]

Possibly the best core mechanic of any game I've so far. It felt really mind-bending, especially on one or two of the puzzles. Great job overall, super impressive execution.

Neato! I love the concept, I like the idea of teleporting to the spot you picked in the mirror you have.

Like a few of the previous comments I also had problems with the controls, it was pretty hard to move around. The platforming sections during the fitness training will probably less frustrating than it have to be after those get fixed.

Also like Felix from earlier I also ran into the bug where you try to teleport into spikes and you get stuck in an infinite loop. A way to manually restart the room would solve this, I believe.

The main reflection mechanic worked pretty well, but I didn't like the platforming mechanics

So, here's some ideas to make first perso platforming more fluid : 

- Air friction : when the player lets go of the control keys, they should stop pretty quickly while in the air. This is to correct for overshoots easier, basically when a players jumps to far they simply have to stop pressing forward at the right time to land on the platform. 

- More air control : most first person platforming games give the player a lot of control over their momentum while moving. You cut down almost all acceleration while in the air, meaning I had to guess the right speed and angle before leaving the ground and couldn't really correct my trajectory. 

- Single press jump : unless it's extremely justified, most first player platforming games will use a single height jump, accessible by pressing the button, no need to hold down to gain height. In 2D games, this concept is useful because you can clearly see the height between your character and the ground, allowing you to precisely adjust. You don't have that kind of visibility in first person, so asking your players to guess the correct height won't work. 

Besides camera issue, and the fact that I’m not very good at parkour, this is a cool game and a fun idea !

I couldn't quite figure out the central mechanic for a while, but I started getting the hang of it and enjoying it towards the end of my time with it.  I ran into a couple bugs though.  First, in the first room with a second mirror, I ended up out of bounds on my first attempt.  I proceeded to fall off the map and had to close and reopen the game, starting from the beginning.  That room worked right away the second time, but in the room after that the camera kept getting caught on walls, and after teleporting into a spike while trying to fall on the narrow platform I got trapped in some sort of infinite loop.  There's a good foundation here though, good work

Great work. The mechanic worked perfectly through the whole demo and it was fun to use. I felt like I was teleporting via selfie. The only issue was the platforming, which was a little wonky at times. Awesome game, congrats on the submission!

Really like the main idea, was fun to play, my only complains are jumping from platform to platform sometimes felt like i was pushed by an invisible force and that it was sometimes kind of difficulte to see where i was aiming with the mirror (mostly when aiming in another mirror). Still fun and the idea is good👍

Neat idea, I really wish I had air control for the platforming sections though.
