Well I definitely was not expecting a guy pulling his eye down staring at me when i booted the game. But other than the gameplay was quite.,. interesting. Weird to get used to, as most mirror style controls are. But interesting.
The little extras for helping with controls were nice to have, helped me orient myself sometimes. Although there is a very blatant bug where you can just phase through the dimensions and all the mobs of either dimension seem to only aggro to the "player" of that dimension, and unfortunately, they can't travel between the mirror and real world.
Very helpful for high scores, not so helpful for being challenging.
Otherwise though mechanics wise it was an interesting setup, I do feel like the stamina was a little weird, the fact that s it's eyeballs aside, it was a little weird in the fact that you drop your weapon when you run out it seems. Which added a lot of extra difficulty, especially considering it seems like you can't directly pick it back, which was a little hard to plan around considering I had to dodge both sides of the mirror at once and also try and get to the unique pipe spot.
Overall though a very very unique mechanic that is just as usual like I said with mirror controls, weird to control, but that adds to the challenge in this sort of game, I do feel like the fact that the pipe is dropped on loss of stamina might be a little too hard. Just because you have to dodge both sides of the mirror at once. But who knows.
