Your game has one of the most unique concepts that I have ever seen. I also think that the puzzles themselves are composed nicely, and the difficulty of each one corresponds with the progression of the player.
My only suggestion would be to add a tutorial level to explain the mechanics better because I had initially thought that pressing "Q" just produces a clone that appears in the place of the player and cannot move by itself.
Amazing work.
I really liked the concept of your game, and I don't think that I have ever seen a game with a similar idea as yours. The art was also very pleasant to look at and fit the concept well.
However, you might want to either tune the jumping mechanic to allow the player to jump further or fix the collision masks on the platforms. Unfortunately, I could not make it further than the Ancient Egypt level because the player simply doesn't jump far enough to reach a certain platform. Moreover, once a layer misses a jump and falls to the area between the elevated platforms, it's impossible for them to get out without restarting the game.
I think that your game has a lot of potentials, but the issues I described need to be fixed to allow for a better player experience.
I really like the environment and levels of your game. I think that you managed to create a great atmosphere of a space adventure and you conveyed it to the player well.
The objective is also clear and gameplay is fun, and I would actually say that this is a rare case where no tutorial level is required.
However, I think that your levels could be improved by adding a mini-map in the corner of the screen because I was often lost and had no idea where to go. If this was intended to make the player explore the world, I still think that a mini-map would only complement this intent. Also, I had no idea when the car received damage, and it just exploded for me at some point. I think that a simple meter representing its health would be useful.
Overall, this is an interesting concept with excellent execution.
