Awesome game! Really nice puzzles and fits the theme well. I really liked the mechanic of being able to change characters 

One small thing tho, the movement was bit counter intuitive sometimes.  Since A and D seems to be angle adjustments based on the characters forward directions. If the character was facing "down" having to press D to face left seemed a bit weird. Personally in a puzzle game, I prefer movement that are more simple "up down left right" type movement (So I could focus on the puzzle, not the movement). But again, that might just be my preference. 

Overall really cool game! 

Great puzzle game. I did not have the time to play through all levels, just reached the first one where you encounter lava. After first having some problems with the controls it played very well after I found the camera perspective change. I would have preferred either wall getting see-through when behind them or the ability to turn the camera by holding the right mouse button.

I think the three different "persons" are a nice touch for the game. Great work.
